Quoted from TomGWI:Why would anyone offer/pay more for one item? Seller sounds like a real Dbag. Seller should have corrected the situation beforehand and refunded the money or inquired why the buyer wanted to pay "more".
I'm surprised it took so long for someone to say this ^^^^^^^^^^^, because ^^^^^^+ "Thanks for the extra $10, DB" = Seller is a stupid, greedy, inarticulate, unedumacated, moron.
