The price at the cash register ticked higher in October, though it was driven by the cost at the pump and on the lot.

Energy prices and new car sales (the highest in 28 years) pushed consumer prices upward in October, they're still cheaper than they were a year earlier. The Labor Department reports that consumer prices edged up 0.3% last month, a tad higher than the 0.2% anticipated. Take food and energy out of the equation, and inflation rose 0.2%, again ahead of the 0.1% that analysts expected.

BJ's Wholesale Club (BJ), whose competitive colleagues include Costco Wholesale Corporation (COST) and Wal-Mart Stores, Inc. (WMT), issued Q3 results earlier today. According to TheStreet.com, adjusted earnings of 45 cents per share met expectations.

And apparently that wasn't good enough for the traders. As of this writing, shares of BJ's were trading down 3% on above-average volume. Was the BJ's story that bad?

If you are hitting Costco Wholesale (COST) for your Monday Night Football party or Thanksgiving celebration, you won't be able to get those cases of Diet Coke. The warehouse-style retailer, which operates more than 550 locations, is no longer carrying Coca-Cola (KO) products in its U.S. stores. That means no Coke, Diet Coke, Sprite, or Dasani water, among other products.

Evidently, the retailer and the beverage giant are embroiled in a pricing dispute. A statement on the Costco website indicated that "Coca-Cola has not provided Costco with competitive pricing so that we may pass along the value our members deserve."

Wal-Mart (WMT), which competes with chains such as Sears Holdings(SHLD), Costco (COST), and Target (TGT), reported results for the third quarter this morning. According to our Before the Bell piece, the famous -- and oftentimes controversial -- retailer beat expectations by a few pennies, earnings 84 cents per share from continuing operations. This was 9% better than the per-share profit earned in the comparable period.

Net sales went up only 1%. They were inhibited by the currency environment. But total sales aren't as relevant as same-store sales when it comes to this sector. If I were a shareholder of Wal-Mart, I would be very disappointed by the comps number, since it is the older locations which indicate how well a retailer is truly doing.

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.
• Agilent (NYSE: A) was upgraded to Overweight from Equal Weight at Barclays.
• 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.
