Diamonds are always popular around Valentine's Day, but lingering unemployment problems and consumer confidence woes have hit most jewelry stores hard. But not Blue Nile (NILE).

Valentine's Day may be a commercialized holiday to some, but there's no denying that its big business. And this coming Valentine's Day may be extra sweet since it falls on a Sunday, making it a great excuse for a romantic night out. In fact, total Valentine's Day spending is expected to reach $17.6 billion this year, up 3.3% over 2009, according to consumer spending researchers at IBISWorld.

That's a big payday, and one that investors should be paying attention to.

As John, Paul, George, and Ringo once said, "Money can't buy me love." While true, money can buy long-stemmed roses, expensive dinners, theater tickets, and jewelry. On the flip side, this money can be tucked away for a rainy day -- the fancy floral delivery replaced with daisies from the grocery store, the pricey meal forgone for the cozy neighborhood spot (or fondue at home).

Many of us have long criticized St. Valentine's Day as a holiday conceptualized and fueled by Hallmark and American Greetings (NYSE: AM). But even more of us fall into its trap, spending a nice chunk of change in mid-February to prove our affection to our significant other.

If you thought Black Friday was just for brick-and-mortar retail, think again. The official start of the online shopping rush is the Monday after the Thanksgiving holiday (Cyber Monday is its name), but don't think that companies like Amazon (NASDAQ: AMZN) and Blue Nile (NASDAQ: NILE) are going to wait that long. They're in the game now. And they want your attention. More importantly, they want you to use the virtual shopping carts at their respective sites early and often. It's really crucial this year, because the economy stinks, and growth in spending isn't going to be great.

According to CNBC, Amazon's strategy is to use very low prices as a way of stopping competitors like eBay (NASDAQ: EBAY) dead in their electronic tracks. This Christmas season, retailers, whether online or not, may find themselves in a no-win situation. They have to lower prices to encourage people to shop. But quality growth in top-line sales is questionable. When managements see the bad news flow about the global recession, they become scared and want to become even more aggressive in terms of pricing. The strategy may work and it may not. It's a vicious circle. Don't get me wrong, the retail industry faces this problem every year at this time, but you have to agree that the current economic cycle is particularly noxious. It's times like these, however, when retailers should want to offer more than just a value proposition. They should want to offer a differentiated shopping experience, a better selection of items. They should strive to offer up a brand image that makes you want to hit their inventories first. They need to step away from trying to undercut all their competitors and instead figure out how to stock the right merchandise in the right amounts. And when it comes to a business like Amazon, I think there's great opportunity to go beyond low-pricing strategies. Quite frankly, I don't care whether Amazon has the lowest prices or not. I find it easier to do some of my holiday shopping on the site. It saves me time during this busy season, I trust the security of the platform, and I know that the supply chain is efficient and reliable. And I definitely think of Amazon first when looking to do online shopping because of its valuable brand equity.
