There's also another problem about I've struck.....The "lost' Item. There's a French online auction house called Delcampe, not many people use it, so the opening bid is normally the only bid. A few times I've won an auction just to be told the item has been "lost".
Last time this happened I bid 20 Euro on an item who's Cat. price was over 200 euro. I asked a question about the item the day before the sale finished, seller checked and told me, nobody else bid and I won it. I thought "great, what a bargin". Then I get an email telling me the item cannot be found, (within one day it went missing), I didn't loose any money, but it did leave a bad taste in my mouth.
