I know, if you don't like it, don't bid, and I'm not going to. I've seen a really lovely t-shirt for sale that I would've bid on for DD had the seller not been charging so much for postage. Even taking into account the cost of envelope, posting, and even the time it takes to go to a post office, it seems like a massive rip-off for someone to charge £3.95 to send an age 2-3y t-shirt, by 2nd class.
Surely if you suspect your item might only get one bid, you should have a higher starting price rather than rip people off on the P&P?
