Old PC in the closet? Here's a way to get rid of it: Sell it to Costco.
Costco, has partnered with Greensight to recondition or recycle your old, but still working, PC. They'll pick up the tab on shipping the PC to them and pay you for the computer.
They take notebooks, MP3 players, LCD monitors, camcorders, digital cameras, game consoles, and phones.
It's gets better yet: There's no trade-in value, but if you have an old CRT, printer, or fax machine, Greensight will recycle it for you and pay to ship the item to them.
The catch: You get "paid" with a Costco cash card. If you're not a Costco member, you can use the cash card towards the membership fee; members can use the card to buy merchandise.
