Not to go too far off in topic but....
Im a firm believer in Paypal, for both buying and selling. I dont mind losing the 2.9%, I consider it part of doing business, and most buyers (95+%) insist on it anyway). I dont like waiting for checks to clear, and money orders still require a trip to the bank. As a seller there are still important steps to take when receiving paymets through paypal(I like using paypal, its a necessary evil, I dont like their business practices though).
As a buyer, nothing is safer than Paypal through a major credit card (a debit card doesnt offer the same protection!).
