Paypal has a pretty high per-item fee of 0.30 / transaction and a reasonably low (and fixed!!) percentage fee of 2.2%-2.9%.

Therefore, if you have an abnormally large average transactions size OR get paid mostly by other businesses, with their business cards OR have an abnormally large share of amex transactions, paypal will be more appealing from a cost perspective than it otherwise would be.

At TransFS.com we include them in the auction results because the answer of how paypal compares in price is actually different depending on your situation.

That's true. My transactions aren't small ($250+) so the per-transaction fee isn't a huge part of the cost.
