It seen to me that bidpay auctions are sometimes a lot cheaper.
Hi Tor,
Thats because it doesn't cost the seller anything whereas with paypal the seller has to pay a fee.
I forgot to mention also that the buyer has to pay a small fee to have the money order delivered through Bidpay. So you might want to take that into account. I'm pretty sure it was only a couple of US$...about $2 I think but I think this may vary depending on the amount paid.
