I've bought four items from the same seller, all cheapo buy it now things. The listings for all of them state 99p postage, plus 19p each item thereafter. There's nowhere for me to adjust the p+p before paying, and I've sent him two emails 12 hours apart asking him to invoice accordingly. He's not replying. Is there another avenue I can take? Can I email ebay? I really wanted the bits, but I can get them from another seller if he's not going to bother at all.
