As I haven't been selling on ebay for long......

[Eck]

...... I've been stiffed a few times, mainly through my own error in postal costs. However I refuse to make others pay the penalty when they make an error.
One new seller was selling a bundle of 15 Rangers cup finals (most were A4) with a £3 start & free postage. Mine was the only bid. I emailed him and put him straight on a few things and told him just to send me the two copies of the 1989 Glasgow cup final.
I kept one and put the other on ebay,it ends today and the bidding is at £8.50. I'm well pleased.
