And the system keep telling bud again because someone else bid higher than me. When I check who won , the winner bid below me . What possible happened there ? I suppose to bid as higher as possible .
Hi I change my mind about the item I won , I contact the seller with time before the auction finish and ask him to cancel my bid. He says he couldn't the item is in my basket but he RELIST the item again wich Im happy with. How I get rid of that item...
I noticed that sometimes on feedback the item appears as a private, can I change all my items to PRIVATE, tell me how.
