Where can you get swagbucks codes?

Firstly, you must be signed up for the site.

Swag codes are posted periodically through the official swagbucks twitter, facebook, and blog pages, and once found, can be entered into the "gimme" section on the homepage for swagbucks. They can also be found through the "swidget" which can be found under the promote tab on the homepage. Lastly, they can be found through the newsletter which is sent out periodically, so make sure you're signed up for that. The codes change regularly, often hourly. So they expire frequently! Stay connected and you will find these swag codes!

But you can take the short cut by regularly visiting sbcodez.com, they regularly update their sites with new swag codes. They also show the timeperiod after which the swag code will expire!
