Ron,
Although I sympathize with you I have to wonder why you accepted those charges to begin with?I know that this has happened to me a couple of times on eBay,where the charges were not listed in the ad and the seller tried to get me to pay some stupidly high charge and I simply told them that this was unacceptable and that they should perhaps "recheck" their postage costs,as what they were asking was way too much.Each time I asked,the seller wound up giving me a "deal"...still not great(maybe $3.00)....but much better than what they had originally quoted me.
Something to consider next time perhaps?
