I'll attempt to answer a question posed in my post in the References section. I thought this forum was more appropriate and I invite everyone to share their experiences, especially the less than stellar ones, so that we can all learn something. Thanks! QUESTION: Hi Sean, What do you mean by "chargeback"? Seems as if I heard this happen to someone on this board before. I ask because I am selling a $600 bike on ****, and listed Paypal as acceptable form of payment. Sorry to get off your original post. Thanks, Steve REPLY: Paypal allows buyers to use of credit cards to pay sellers. So, for example, you do a deal, and the buyer pays you via Paypal with a credit card. Downstream the buyer decides to dispute the charge with his credit card company. The credit card company generally will stand by its customer, the card holder. They credit the card holder's account, and debit Paypal. Paypal responds by debiting your account. You then have to prove you shipped, etc. Paypal supposedly backs the seller if certain conditions are met. If you ship to a confirmed billing address (meaning the buyer's credit card billing address is consistent with his shipping address.) In some cases, due to the policies of the buyer's credit card issuer, an address may not be confirmable. And there's the rub. If you ship to an unconfirmed address, Paypal may not back you if the buyer disputes the charge. So, you may eat the money. There is a downside risk to using Paypal and accepting credit card payments. There seems to be less risk if source of the payment is a bank account because as in the case of a cashed check, a charge back is much more difficult to effect. Paypal does take anti-fraud measures, such as confirming email addresses (albeit anonymous email addresses like yahoo and hotmail) confirming bank accounts, credit cards, etc. I will say that in my case, I have used Paypal as both a buyer and a seller, and thus far have had no bad experiences. I would be interested in hearing the tales of those who had bad outcomes because I imagine I'm ignorant of Paypal's flaws. I'd love to hear some charge back stories. Many companies that have a very dominant market postion become difficult to deal with (ie, Microsoft, ****, AOL, etc.) I have had bad experiences with all three of those outfits because they have a "take it or leave it attitude", and it feels like you are dealing with the federal goverment when you do business with them. Paypal is giving me that vibe of late. No real surprise given that **** owns them.
