The New York Times has an article on how many online retail sites are heavily discounting their prices lately. They give us a really good tip about Zappos, the shoe retailer, and how we can find their shoes way cheaper at 6pm.com.

To preserve the sanctity of their brands and some level of pricing control, some Web companies are promoting discount sites separately from their main brands. Zappos.com, a shoe retailer based in Henderson, Nev., never runs promotions on its site. Instead, it quietly moves shoes that do not sell in six months to 6pm.com, a clearance site it acquired last year, but runs separately. This month, the company is buying more search ads for 6pm.com, where a pair of colorful slip-on Keds sneakers is on sale for $12.73 — 74 percent off the original price on Zappos.com.
