However.. it's not against ebay policy to offer a discount on shipping and handling if you don't use paypal. Or they could just have nebulous "handling charges".. which I'm sure they'll change it to after you report them. The only difference is you'll probably pay more in the end as the seller will now have to estimate more than the average paypal fee in handling charges before listing.
Semantics I know - but ebay specifically prohibiting you to pass on charges from a company they own (while leaving you free to pass on fees from any other online payment service).. sucks.
People who charge high shipping and handling while having a low listing price are just avoiding being screwed over by ebay's fees (which are only getting higher.. and with paypal charges they are double and triple dipping). I wouldn't do it myself, but I can see why they do it and I don't see why you care about defending ebay's profits.
