Ebay bucks not credited

I earned ebay bucks the last few months and spent them this month. When I saw my invoice for the purchased product, I noticed they'd be applied to the price of the purchase and that's the way it should have been. When I looked at my paypal account, it showed they'd deducted the full purchase price from my balance. I have one log in I sell from and one log in I buy from. I think I opened my paypal SELLING account when I paid for the item and that's not where I earned the bucks. Let me try it this was: A - sells B - buys B earned bucks and made a purchase thru that log in. And the invoice showed the bucks used. A looked at the paypal account which is the only one that had a balance and it showed the full amount deducted but the ebay bucks are gone from the B account. Does that make sense? But why did the system let me buy something thru B and pay for it thru A?|||Have you looked at your payment details? The main page will show the total payment made but the detailed transaction info should show the "coupon" used.|||I had to put in a code to redeem my bucks "Be kinder than necessary, for everyone you meet is fighting some kind of battle."|||IF the seller uses a third party checkout, you have to use the coupon code to use the bucks. I'm not sure you can earn them on one id and spend them on another. I'd guess not.
