Yet the online sales seem to be even more alluring. 

This time of year is pivotal for retailers. If you're an apparel retailer, you want your shelves cleared by President's Day weekend, industry tracker Britt Beemer of America's Research Group told Forbes. Spring is vital; it's the only time people might be willing to buy stuff at 20 percent off, or even at full retail if they love it.
