Costco Wholesale Corp. (NASDAQ: COST) is realizing that many of its customers are still living on hard times these days, even the news that the economy is rebounding. That doesn't mean lost jobs will pop back any time soon, and as such, the wholesale retailer will be accepting food stamps at all of its U.S. locations.

People need to eat, and Wal-Mart (NYSE: WMT) sells food. People need to cover themselves, and Wal-Mart sells apparel. You get the idea – the biggest needs may be thin-margin, and their all sure things. Wal-Mart plays in the inevitable, which makes its latest market entry a little less surprising than you might think. Wal-Mart is pushing caskets and urns – depending on how you want your remains preserved. What is a bit shocking, however, is that the brick-and-mortar player is selling its death gear online.

Wal-Mart is using its low price strategy to beat funeral homes, which have seemingly forever been the biggest sales channel for caskets. Prices start at $999 for the low end models and go up to the Sienna Bronze Casket at $3,199. Except for this last one, all models sell for under $2,000 ... and all product ships within 48 hours. The funeral homes are over a barrel on this one, since federal law requires them to accept third-party caskets.

Wal-Mart is supplied by Star Legacy Funeral Network, and both are apparently happy with the first week's sales.

The Bentonville-based retail giant is not the first to get into the gloomy business of bodies. Discount retailer Costco (NASDAQ: COST) is already in the online casket business.

Microsoft's (NASDAQ: MSFT) new operating system, Windows 7, is set to be released on October 22, 2009, but it's unlikely to have an impact on PC prices. So, if you're feeling the urge to rush out and buy a new box, try to hold out until the end of the month. You'll get a bit more life out of it.

Fortunately, PC prices aren't expected to get much lower, so the entire supply chain -- from chips to software -- has nowhere to go but up. The effect, though, has been to put some serious pressure on manufacturers and retailers to keep from screwing up the release.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Alcoa Inc. (NYSE: AA) reported a surprise Q3 profit due to cost cutting; revenue topped estimates as well.
• Avis Budget Group Inc. (NYSE: CAR) said a proposed offering of $250 million in notes could reduce earnings.
• Clorox Co. (NYSE: CLX) earnings prospects garnered it an upgrade from one analyst.
• Coca-Cola Co. (NYSE: KO) earnings prospects resulted in an upgrade from one analyst.
• Costco Wholesale Corp. (NASDAQ: COST) lower Q4 earnings topped analysts' expectations, lifting shares.
• Family Dollar Stores Inc. (NYSE: FDO) higher Q4 earnings beat analysts' estimates but sales were just OK.

BJ's Wholesale Club (NYSE: BJ - option chain) stock is trading lower today after the company reported its same-store sales slipped 0.5 percent in September. Analysts were expecting a 1 percent decline, but traders saw competitor, Costco (NASDAQ: COST) post a 1% rise in September same-store sales and wanted more from BJ. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on BJ.

This morning, BJ opened at $35.90. So far today the stock has hit a high of $36.13 and a low of $35.90. As of 11:20, BJ is trading at $36.10, down 96 cents (-2.6%). The chart for BJ looks bullish and S&P gives BJ a positive 4 STARS (out of 5) buy ranking.

Costco's (NASDAQ: COST) profits are off 6% for its fiscal fourth quarter. A stronger dollar and increased employee benefits costs are cited as the reasons. Nonetheless, the retailer did beat analyst expectations.

The company, which operates warehouse clubs, pulled in earnings of $374 million (85 cents per share) for the quarter ending August 30, 2009. While this is down from $398 million (90 cents per share) a year earlier, it was good enough to top the 77 cents per share that analysts polled by Thomson Reuters had forecast.

Costco Wholesale Corp. (NASDAQ: COST), the popular warehouse store that competes with BJ's Wholesale Club (NYSE: BJ) and Wal-Mart (NYSE: WMT), will report Q4 earnings on Wednesday, October 7. How will the company do?

Don't look for growth, my friends. According to Earnings.com, estimates from Wall Street say that Costco will produce 77 cents per share in income. Unfortunately, that represents a 16% drop in the metric. Surprising? Maybe a little. After all, we're still suffering a bad economy, and you figure that people would want to cut costs by leveraging the bulk buying power of the Costco business model.

Alcoa Inc. (NYSE: AA) kicks off another earnings season this week, and analysts surveyed by Thomson Reuters are looking for another net loss for the third quarter. Can we take that as a sign of things to come, or as a bellwether for the economy? Well, barring a big downside surprise, this will be the third narrower quarterly loss for Alcoa. But while Alcoa beat estimates in July, it missed them in April. Alcoa's shares, on the other hand, are up 145.6% since the March low, which is well more than twice as much either the Dow or the S&P 500.

During its third quarter, New York-based Alcoa continued restructuring efforts, remained a part of the DJIA Sustainability Index, and declared a quarterly dividend. It is expected to report a net loss of $0.12 per share for the three months that ended in September. That compares to a profit of $0.37 in the same period of last year. Third-quarter revenue is forecast to have fallen 38.3% to $4.5 billion. Analysts so far expect to see a profit in the fourth quarter, but not for the full year. Alcoa has missed earnings expectations in three of the past four quarters. The long-term EPS growth forecast is 20.0%, again much better than the S&P 500. The First Call consensus recommendation is to hold AA; CNBC concurs that now is not the time to buy. At $12.82, shares are 30.0% higher than three months ago, but 33.4% lower than a year ago.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Activision Blizzard Inc. (NASDAQ: ATVI) shares rose after it reaffirmed its full-year earnings and sales outlook.
• Automatic Data Processing Inc. (NASDAQ: ADP) will have low double-digit EPS growth, predicts one analyst.
• AutoZone Inc. (NYSE: AZO) posted a decline in earnings but a small rise in sales, sending shares lower.
• Bed Bath & Beyond Inc. (NASDAQ: BBBY) posted better-than-expected Q2 earnings and higher revenue.
• CarMax Inc. (NYSE: KMX) rallied to a new 52-week high after topping analysts' Q2 earnings expectations.
• Carnival Corp. (NYSE: CCL) reported better-than-expected Q3 results and raised its full-year guidance.

Analyst upgrades:

• Roth Capital upgraded MicroStrategy (NASDAQ: MSTR) to Buy from Hold and raised its target to $90 from $70, citing encouraging Q2 results, new product cycle catalysts, a lift from Europe, and cost reductions.
• William Blair upgraded Costco (NASDAQ: COST) to Outperform from Market Perform after meeting with management as it believes sales and earnings could beat expectations over the next year.
• Credit Suisse upgraded Novellus (NASDAQ: NVLS) to Outperform from Neutral and raised its target to $29 from $23. The firm cites higher Samsung capex forecast, high leverage, and low expectations.
• Home Properties (NYSE: HME) and Equity Residential (NYSE: EQR) were upgraded to Outperform from Market Perform at FBC Capital, while Douglas Emmett (NYSE: DEI) and Duke Realty (NYSE: DRE) were raised to Market Perform from Underperform.

• Cytec Industries (NYSE: CYT) was upgraded to Buy from Hold at KeyBanc.

Costco's stock has trended up nicely, from $47.21 when first recommended on May 19, 2009, hence it's not as cheap as it was then, but a case can be made to establish/add to a position on a pull-back to $53-55. Therefore, I'm reiterating my Buy rating.

Costco (NASDAQ: COST) remains a value-oriented consumer warehouse with an appropriate middle-income, near-upscale product mix that's likely to draw in many "suddenly just middle class" consumers whose incomes have been constrained/lowered by the current economic era. Translation: market share gains for COST.

Analyst upgrades:

• Jefferies upgraded Warner Chilcott (NASDAQ: WCRX) to Buy from Hold. The firm views Warner Chilcott's acquisition of P&G's (NYSE: PG) pharma business as a positive given its attractive product fit and purchase price.
• ThinkEquity upgraded Google (NASDAQ: GOOG) to Buy from Source of Funds and raised its target to $550 from $400. Previously, the firm thought Google Street estimates were too high and that low single-digit growth in Q2 and Q3 would cause multiple contraction. They said their thesis played out fundamentally but they were wrong on the stock. Given Q2 has past, the analyst raised estimates above consensus and expects an in-line Q3 and for shares to outperform as the economic cycle turns.
• Bernstein upgraded Diageo (NYSE: DEO) to Outperform from Market Perform and views Diageo's valuation as attractive. The firm expects 2H09 results on August 27 to mark a bottom in weakening top-line trends.
• Costco (NASDAQ: COST) was upgraded to Market Perform from Underperform at William Blair.
• Lowe's (NYSE: LOW) was upgraded to Overweight from Equal Weight at Morgan Stanley.
• Siemens (NYSE: SI) was upgraded to Buy from Neutral at BofA/Merrill.

Due in part to the U.S. government's "cash for clunkers" auto trade-in program, retailers across the country will see a weak July sales month. The discretionary dollars that customers would have spent in retail have been going toward newer cars, and with jobs continuing to be lost every month, the squeeze on retailers -- even with "back to school" season in swing -- will continue.

Historically strong retailer Wal-Mart Stores Inc. (NYSE: WMT) has not been completely immune to the retail sales slowdown that has been in effect for quarters now, but it too may see a lower-then-expected July same-store sales figure. Other retailers like Costco Wholesale Corp. (NASDAQ: COST) will be in the playing field of retailers that report July numbers soon and will mark the 11th consecutive month of retail same-store sales declines among retailers in the U.S.

PriceSmart (NASDAQ: PSMT), an operator of warehouse clubs in Central America and the Caribbean and headquartered in San Diego, announced results for the third quarter on Friday. Judging by the reaction to the stock, I'd say the market wasn't too thrilled by the company's performance. As I write this, PriceSmart shares are down almost 14% on heavy volume in afternoon trading.

Net warehouse sales increased nearly 8%. Total revenue went up by a similar amount. Earnings came in at 30 cents per diluted share. Unfortunately, that means that PriceSmart's bottom line declined by 17%.

Kroger (NYSE: KR), a supermarket chain that competes with Wal-Mart (NYSE: WMT), Costco (NASDAQ: COST), and Supervalu (NYSE: SVU), issued its Q1 earnings report today. Not much came of it, though. The stock, as of this writing, isn't doing much in afternoon trading. Too bad for shareholders, because the bottom line beat the analysts.

According to the earnings preview from Michael Fowlkes, Kroger was expected to deliver around 61 cents per share. Well, Kroger earned 66 cents per share. The number improved last year's performance by 8 cents. Revenues were essentially flat. Same-store sales increased a little over 3%. When you think about it, Kroger did pretty well.
