ThinkGeek cuts up to 50% off Valentine's Day Gift Ideas, with prices starting at $4.99. That's a strong discount on many of these items from ThinkGeek, although we saw up to 60% off a Valentine's selection a year ago. (We up to 80% off a selection of winter clearance items a week ago.) Shipping starts around $6, but orders of $75 or more net free shipping. A couple best bets:
Mars Planet Pendant for $4.99 + $6 s&h
Chillpod Wine Bottle Quickchiller (pictured) for $49.99 + $7 s&h
