I am sorry if I am not the first to ask this, but I couldn't find any related thread in search (more because I didn't knew what to search exactly) I have won an auction is a very good price (nearly half the actual price of that product ) and amount payable is $100 (which is quite not a small amount) Now the seller is not responding. It is clear that he didnt expected his auction finish too low. If I leave a -ve for him. He will surely do that to me (his itrader is too low, so it is me who will be hurt more) Any suggestions? Is the seller bound to complete the deal is the buyer has won his auction in DP ?
