Costco Trade-In Program (aka Cash for Electronics)
 

Costco has a nifty little trade-in program where you can get cash for your unwanted electronics. It's not much (looks comparable to other sites) and it's Costco Cash but it's not a fly-by-night operation.

Looked at the site, but without going any further....do they accept non-working items?

Not sure. I put a camera there that doesn't work and it said no and provided a link to recycle electronics. But it's also an old camera.

Here's the same company without the Costco referral and you can get paid via check, paypal, WalMart gift card, Amazon.com gift card or donate the money to charity.

ETA: I found an that says Gazelle only takes working electronics. It also references NextWorth as a place to sell. They are offering $15 more for my BB then Gazelle.
