What can you do to get some money back from a 2.0 Megapixel digital camera?

Exilim Casio

Take lots of pictures then sell them to AP

sell it on e-bay

Sell it on ebay.

It's good for basic digital photos.
I use an old 2.3 Megapixel for my listings.

as in you just bought it and want to make it worth the money? In that case, go to craigslist.com and offer to take pics as a freelance photographer in whatever capacity you feel comfortable (headshots, family, portraits, event photography, nudes,etc.). Offer a low price and you'll rack up. If you mean that you want to sell the camera, you can also do that on craigslist or ebay. Craigslist is free and faster.

A 2.0 MP camera these days is not worth much at all, especially when the newer releases are mostly 6-10 MP.
It might make a good paperweight.......

You can try to keep a lookout on camera promotions that has trade-in. I know that Casio Exilim just had one during Comex 2006 (trade in any digital camera to get SGD$100 off EX-Z600), mayB you can check out whether the promo is still on.

Alternatively, u can try Cash Converters, but I can tell you they won't even pay u $50 for that.
