If you haven't already, please check out the new page on the site "misc. income".  I've added a couple of sites that really don't "fit in" with anything else I've done. 
Most of these sites pay cash back for shopping.  I order a ton of things via the internet, and one of my rules is to never buy anything without getting cash back twice (once via a site such as MyPoints or Quickrewards and once via my credit card). 

MyPoints is a wonderful site in that regard. 
MyPoints is an easy program and I have been paid by them.  I don't know the exact minimum to cash out, but it isn't high.  Plus, they offer a ton of gift cards (along with other thing) as rewards.  When I ordered mine, I got it in three days flat.  Very fast turn-around. 
How to earn:
1) Cash back.  They have hundreds of merchants (including E-bay!!!) and the "cash-back" rates are excellent.  One of my rules of shopping online is to never buy anything without getting cash back (either on MyPoints or Quickrewards). 
2) Daily clicks via e-mails.  I do these because they really do have some interesting offers come in.  Plus, I find out about deals and specials that I wouldn't have noticed otherwise.  These points really add up. 
3) Supposedly you can earn via other things- such as free samples, surveys, games, etc.  I haven't had time to explore these features, but should I find time, I'll let you know if they work like they're supposed to!
