For those that participated in the Paypal Spring $15 Cash Rebate promotion, you should be receiving your rebate transfer shortly.
I just received an email from Paypal stating the first (of two) $15 rebates was deposited into my account.
The recent promotion promised a cash transfer to your Paypal account by May 28. I assume the rebates are being processed according to purchase date, so I should be getting the second rebate (into my other Paypal account) within a few days.
Good deal, Paypal!
EDIT: I should mention the qualifying purchase using my first Paypal account was on March 19, and the additional purchase using my second account was on March 24.
UPDATE (04/27/2007): Received the email for my second $15 rebate.
