Second, it's also Summer of Swag so every 7th search gets 59 Swagbucks today (so far I've only received 16 26)

OH wait! I guess I have 4 things..
Fourth, if you enter your birthday in your Account Details you'll get 50 Swagbucks on your birthday. :)
I've been searching with the Swag Toolbar since December and I've earned about $75 in Amazon gift cards. I get 10-30 a day just from normal web searching, plus if you refer someone you get what they get up to 1000 Swagbucks. You can get other prizes besides Amazon Gift Cards, but I think it's the best value for your hard earned web searching. :)
