$10 PayPal credit with $20 photo order

This deal has a lot of caveats and rules, but it could save you as much as 50%. Here's what you have to do.

Log in to Walgreens' photo site. Submit an online photo mail order for $20 or more, not including shipping and taxes. Submit the order by September 30, 2008 at 11:59 p.m. CT and pay for the order using PayPal. You must have a confirmed U.S. PayPal account in good standing to be eligible.

Look for a $10 credit to your PayPal account three to four weeks after the promotion ends on September 30. It's a long time to wait but free money is hard to come by.

Caveats: Offer excludes custom framing service and W Photo Gift Cards. Maximum credit is $10. May end sooner than September 30, 2008. A few PayPal transactions are excluded. Read the details here.
