can I approach a buyer that didn't sell something to make an offer?

[brimfull]

Is this allowed?

There were no bids for the item.

Could I make them an offer or ask them to relist item?

Yes, we do it all the time. Best to get them to relist at a buy it now price so you still have ebay protection IYSWIM. Oh and agree to a time when it goes on so no one else snaps it up first.

Its worth a try. I have re-listed items before for buyers who forgot to bid.

right thanks
