Perhaps the original buyer never paid up and the seller has changed user id and is now selling again?? :-?
However, whenever I re-sell something that my previous buyer has not paid for, I do state that on the relisting and dont change my user name!!
Maybe they had a dispute and the seller wad temporarily suspended, and has decided after being reinstated to start again with a new user name?? :-?
Of course, there is always the rogue thought from satan that its all just a scam, but I don't like to judge when I don't know!! :-D
