PayPal (which is owned by eBay) are a bunch of greedy fee grabbing ----s. FeeBay and PayPal both need to rot in hell and die a horrible and painful death. That company is so damn greedy it's not even funny. When a seller sells anything on eBay, you have to pay: listing fees and final value fees. Not only do they charge the final value fee based on the price that your item sells for, but they ALSO take a cut of what you charge for shipping too! Then on top of that, PayPal takes their fees. In the end, those -----es take nearly 20% of your money. It's highway robery and it pisses me off to no end. In all honesty, I'd rather NOT accept PayPal because of the fees, but since they seem to be the standard for online payments, what option do you have besides alienating a huge number of people?
I know nothing of liberty reserve other than it's another payment processor. That is all. Nobody that I have encountered has ever asked if we accepted it, so I don't feel that it's very popular, at least not yet.
