Paypall has sent me three emails about their latest promotion if you use them, there is a possiblity to receive 10 or 100. I have three times to access it but Paypal never acknnowledges me.. What a terrible terrible system. Same thing with one click purchase.
To make you feel better it wouldn't have made a difference if you did sign up.
I was signed up, spent the $150 and yesterday was the day we should have heard from them by, but nothing. Looks like multiple times before they've created such promotions and never followed through on rewarding those who met their terms.
