In September, Swagbucks is giving away an extra code each day, but only to those who have downloaded the toolbar. It downloads in just seconds. Thirty extra codes in Sept.? Very nice. There are a lot of prizes that are 30 points an under. Mp3 downloads are just 1 point.
A $5 Amazon gift card is 45 points, so just the extra codes in Sept. will get you close. Use the site to search and you'll likely get the other 15 very quickly. I just cashed in two $5 Amazon gift cards when buying some shirts. It was great to get $10 off my purchase.
