To those of you who sell to soul & ska collectors on Ebay, beware of northerne1960 (from France) and billymomma (from the USA).
They have both bid on items (OK, £15 and £26 isn't a great deal, but it's the principle), have not paid up, and have both allowed an Unpaid Item Dispute to run its course. Deadbeat timewasters, both of them, despite the fact they have 100% positive feedback over the past year.
In the case of billymomma, she bid on an item of mine. She won the same item from another seller at a slightly lower price, but did not cancel her bid with me. Obviously, she chose to ignore the dispute and strike against her.
What really p*sses me off is that we can block these timewasters, but we can't leave them good, honest negative or even neutral feedback for what they've done.
My advice to you, if they bid on your items, is to send them a message making sure they'll pay, or otherwise remove their bids and block them.
