Last month I must have used the $10 google check out coupon at least 5 times on my orders over $30. This month PayPal is getting into the act by offering $20 off orders over $50 at their checkout.

The trick is you must submit your email address to PayPal before Nov. 22nd.Then spend your $50 between Nov 23rd and Dec 31. Like that is going to be hard during the holidays.
I used all my Google coupons on items that were already on sale at discount sites. I bet this coupon will not make it past Black Friday for me.
