Seller asked for PayPal fees after the sale. Should I pay them or not?

Definitely not to pay 3% PayPal fee. If he disagrees, ask him to refund the amount you have paid, and terminate the deal. If he refuse to refund the money, report to PayPal to resolve it. Don't worry, you won't lose your money because PayPal will pay you back and deal with him just like credit card company. For your information, when using PayPal to pay a large amount, use credit card and PayPal to have double protection. In the case PayPal takes too long to resolve the issue, call credit card to put amount on dispute. Finally, if the issue is not ended up the way you want, report the incident to Audiogon, or eBay, and give him negative feedback.

IMO, it should be the seller's responsibility to absorb paypal fees since he/she is using the services of such 3rd party payment method. I am not pleased to pay other fees other than the offer price. I dont understand (and i refused to) why sellers are passing the fees to buyer since they always have the option to include %fees to there offer price. These happened to me in one of my transaction here in audiogon. After making offer for an item which he accepted, he send me a second bill with additional fees. I ask the seller to remove the additional fees since the first bill did not reflect Any additional fees which he accepted it. The seller didn't gave me option so i old him that I'm not buying the item anymore. The seller got irritated and became arrogant and threaten me to report to audiogon which he did plus leaving a negative feedback that "i didn't pay for the product i purchased". I explained my side to audiogon that there was a misunderstanding in the transaction and there was no final sale done. Afterwhich, audiogon reversed the fine (charges for buyer backing out )for buyers but did not removed the negative feedback and told me that they are going to review it.
Too bad that audiogon sided with the seller instead of protecting the buyer. 

So buyer beware and always ask for out the door price before paying...

Someone above pointed out that it is against Paypal’s rules for a seller to ask the buyer to pay the Paypal fees. Unfortunately, a lot of seller’s ask/require that buyers do pay the Paypal fee, or circumvent the fee by asking the buyer to pay via friends and family. To head this off, before I send a Paypal payment I try to remember to inform the seller that I will be paying for goods and services, and I add up the price and any shipping. This gives the seller a chance to "correct" the final price, and gives me, the buyer to back out or renegotiate. Usually, if someone tries to stuff in last minute charges, I walk away on the basis that they have not been honest. And what if something goes wrong; I don’t want to have to deal a person like this if the item arrives with shipping damage, etc. On walking away from a deal, rarely is a deal a 'must have' deal for me. Letting your acquisitiveness cloud your judgement regarding safety is bad idea. (Acquisitiveness is a mortal sin for Catholics!) Another 'must have' item will probably show up for sale soon, I have learned.
Paypal Friends and Family versus paying for Goods and Services (or merchandise): If you don’t understand the difference, there are no fees to send funds to friends and family. Some sellers of merchandise want to be paid via this method, as it saves them Paypal fees. It is also fraud against Paypal. If you are okaying defrauding Paypal, think about this:
you pay good money for something and pay via the Friends and Family method. The seller sends you a brick. Try going to Paypal and getting them to return your money.  They will say, "what merchandise?" They would at least put a check on your account as someone who doesn't follow their rules, and who, knows? They may kick you off.
End of rant. Sorry, if I had more time I would write a shorter pos

That sucks, @biggiglypanda.
When I list an item for sale, I absorb the Paypal fee. Most buyers will negotiate a price, and if it's too low, I'll remind said buyer that I am paying the fees. IME, the buyer will then accept a fair price.

Audiogon listings are very different than Ebay, where it's the policy that the seller pays all fees. Just look thru the Agon classifieds and see how many sellers are charging a 3% Paypal fee.

If it was not listed for fees in the ad .then you are in no way obligated to pay this .
 If you don't want to pay ,then donot if he does not agree .he has to give you a full refund .for you fullfilled your end of the bargain.
