I was wondering if anyone knew of some good sites where you can earn online gift cards (I'm saving up for the holidays). I'm already part of a few of them, but wanted to know what other ones people have joined. If you're interested, I've written a post about the ones I use here.

Also, anyone else have good ways to make a couple extra bucks before gift giving season?

Admittedly it's not a website, but if you have a smartphone, I use the Shopkick app regularly. When you walk into certain stores, you can check in for "kicks", and scan barcodes of some of the items in store for more. After you have a certain amount, they can be exchanged for credit towards a bunch of different stores.
