By using them as your search engine, printing and redeeming coupons from their site, and searching for "Swag Codes" you'll earn them quickly. It doesn't take much time or effort but before you know it, you'll have enough to redeem a prize (or two, or three...)!
Redeem your prizes in the Swag Store or redeem them for Amazon gift cards!

P.S. Collect enough SBs and you can do some Christmas shopping on Amazon!
