In order to take advantage of the cash back, just create your Swagbucks account when prompted (it takes less than 30 seconds) and then you're all set! Your cash back comes in the form of SB points, which you can redeem for gift cards to places like Amazon, Target, Walmart, Starbucks, or get PayPal cash!
As a special bonus, if you sign up through me you get a 300 SB ($3) bonus when you earn your first 300 SB before December 1st! This site's a great way to extend your shopping budget, especially around the holidays!
