You get 2% back each time you make a purchase. That means 2% of your order (excluding shipping) gets placed into your REWARDS account. You can cash out by applying your REWARDS balance when you have earned $10 or more.
You can view the rewards amount by viewing your account from my account link. You must have an account & be logged in to earn rewards money. If you select to "checkout without registering" then your REWARDS money will not be applied to your account.
REWARDS cannot be used to pay for shipping or taxes.
