Ok go here and create an account with OC Daily Deal. They will send you an email – make sure you verify your account. They will give you a $10 credit when you join. Look for the deal for MrsFields.com $20 for $10 voucher. Click to buy it and your total will be $0! They will send you a email about how to use your voucher!
You could probably have this shipped to someone as a nice gift! I got my voucher in a few minutes!
Not sure if you will get cash back but when you get your voucher go through Shop at Home - you may get 7% back and a $5 sign up credit!
(Thanks, Mojo Savings!)
