Ok, I didn't realize I haven't posted my fave sites on here before! Here's my favorite sites that I HAVE made money from. They are all free, otherwise I wouldn't waste my time. I'll post the links below.
Hits4Pay is an GPT site. You have your own inbox on thier site, so no SPAM! They pay you with paypal. You can cash out at $25.
DealsnCash is a site made by the same people from Hits4Pay. The only difference between the two is you can cash out at $30 instead of $25.
There is no cash out minimum for this site and they also pay through paypal.
I also LOVE bzzagent, mypoints, mylot, freeride, and moola.
Bzzagent is a site that you don't earn money, but they send you free products to try and use just for your opinion in return. Thus far I've gotten 5gum, Listerine Whitening Strips, Smuckers Uncrustables, and Clearasil makeup remover cloths to name a few. They also give you samples and REALLY good coupons to share with your family and friends. You can also earn mypoints points on this site.
Mypoints is a site you can trade points for money. Simply print coupons, click on emails they send, etc.
Mylot is a blogging/forum site. They pay through paypal.
Moola is a free gaming site. So if you're looking for a way to kill time at work(lol, jk) this is the site for you!
I just got paid from freeride today. I redeemed my points for a $15 amazon gift card.
I would post links to these last sites, but they are by invite only. If interested email me at email@example.com with your email addy and I'll send you an invite. Any questions are appreciated, please post them below.
I'm also a member of inboxdollars but I haven't recieved payment from them yet.
