EBay coupons?

i have a paypal account and an ebay account, i won this item and payed using my paypal, including postage it came to 拢20.00, but it said i had a 拢2.50 coupon and deducted 拢2.50 off the total, but i didnt even know i had a coupon and didnt put in a code, i had an email confirming payment for 拢17.50 , but when i look on paypal account there is no mention of the coupon and just says 拢20.00, whats going on, can anyone explain?EBay coupons?
With paypal no one can explain it has a mind of its own and is very moody and expensive.





they have a phone number though,





ps, so does ebay now I couldn't believe it eitherEBay coupons?
do you spend alot using paypal? if so, it could be an incentive to spend more
