I think that it's your own fault if you are upset about the postage. As someone else said, the fee was disclosed on the auction, and you therefore had an option not to bid on the item. As someone that DOES measure out and charge very accurately, I would think you'd spot that the shipping/handling fee was way off anyway.
As for people that don't like the PayPal/Ebay fees charged... You have the option not to sell your item on Ebay. All these fees are disclosed when you sign up (I've only recently started using Ebay, and I DID take the time to read all the crap before disclosing all my information). There's an option to put a reserve price on your item. Perhaps people should decide how much they need for the item, add on the ebay/paypal costs, and set a reserve accordingly.
Finally, if you have your own business, you would realise that the Paypal fee is not unfair. Every time you put a cheque into a business bank account, it costs a flat fee. Every time a credit card transaction is made into the account, there is also a percentage charged for the transaction. It's standard practice, I don't think Ebay/Paypal's fees are unreasonable. I think if you had a special bank account for your ebay stuff, and had it set up to where you could receive funds from a credit card, the cost would be similar (only the bank would charge you for the ability to receive funds in this way anyway, so Paypal is most likely a cheaper option)
