Have you heard of a "closet boutique"? This is a new phenomenon that The Weekend Journal recently reported on where women open up their closets at home to sell designer clothes. Closet boutiques are typically advertised on Craigslist.

Last month, there were 715,000 postings for closet boutiques on Craigslist -- more than double the amount than last year at this time.

One caveat here, obviously: You'll certainly have some crazies come into your home if you have a closet boutique sale. Be sure to store away all your valuables, and make sure you have enough eyeballs on hand to ensure that people don't wander around your home and shoplift.

For buyers, of course, a closet boutique offers the opportunity to pick up designer duds at a tiny fraction of their new cost.

In related news, Amazon has announced it's getting into the used gaming market with a new trade-in service. Those who have old games to trade in will get Amazon credit to spend.
