Here’s a few sites I enjoy:

Apparel:

Pajamas at Bargain Prices – Hey, one of the perks of working from home is being able to wear pajamas in “the office” when the mood strikes. The great prices keep me going back again and again.

Geek Bouteek – A plethora of tees for geeks. Great quality, great pricing.

Think Geek – Apparel, gadgets, toys, and other cool stuff.
