With regard to using paypal, we have closed our paypal account and will never use paypal again. The reason is because our paypal account was hacked. Paypal claims they have no knowledge of such, and ebay offered us no recourse either (it was opened via ebay and hacked via ebay). Someone was selling product under our ebay and paypal accounts, and then changed the passwords so that we could not get in. Plus, they were not sending the products for which they were collecting payment. They did not change the email address, so we got angry emails from THEIR customers who were getting screwed. Luckily, we never kept more than about 80 cents in the account, so we didn’t get robbed, just had our name & account dragged through the mud. Canceling ebay and paypal put an end to our involvement in the fraud, tho I don’t know if it changed anything the other person/entity was doing.
To make matters worse, a cousin had been selling lots of stuff on ebay and taking paypal payments. They had almost $1,000 in the account when it got drained. They, too, had no recourse and lost it all, only fixing their “problem” by canceling their paypal account.
Finally, I’ve read on one prominent ecommerce site that more than 60% of the transactions were aborted when the consumer got to the paypal payment screens. He solved the problem by having his own merchant account. Now, almost 98% of the transactions are successfully completed. This indicates to me that paypal is quick and easy, but probably not the professional quality that some would like – in contrast to having a merchant account that appears much more professional and private.
