Here is why I hate the "paypal only" policy despite accepting
paypal.

I sell a lot of stuff that is picked up locally. Paypal gives me no
seller protection if a buyer pays via paypal, picks up, and later
claims that "item was not delivered". In such a case, they would
refund the buyer without question. They require a tracking number from
UPS or USPS as proof of delivery. Signed statements "item picked up in
described condition" mean nothing to them. So they are demanding that
I accept payments and expose myself to buyer fraud. All so that they
can make extra bucks on the paypal fees.
