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


I recently purchased an item and after accepting my offer the seller asked for PayPal fees (3%). I checked the listing and nothing was listed in the ad about my paying the fees.  I have already payed half the fee but I'm not sure if I should have paid the full amount. Changing the deal after accepting the offer feels wrong to me. Looking for guidance.

It is not contrary to Paypal terms of service to ask for the fee. That rule only applies to Ebay. It is an Ebay rule, not a Paypal rule.
The whole PayPal thing sucks.  Man, I miss the day when we sent each other a money order, ship the item when you get the $.  Done deal dude.
Sigh...
There is nothing carved in stone that you must use PayPal. I have sold here and taken certified or personal checks as payment. Of course you don't ship until the check clears.

Ebm, the whole point is that the seller neglected to mention the fees.
The OP (buyer) isn't being a cheapskate, just nonplussed that the seller is asking for the fees after he received payment.

I guess the OP as 2 choices:
Either ask for his money back and cancel the deal.
Or,
Pay the fees and be done with it.

Though, if it were me, before doing anything, I would contact Audiogon and ask them what they feel is appropriate in this situation.
I also hope the seller is following this thread. I would like to hear his/her version of the story.- Just to be fair.
Miscommunication happens. It would be nice if both parties could come to an agreement.
