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.

This happened to me on my first deal here on Audiogon. I was disappointed at the lack of integrity by the seller but since I had already made payment I paid his ransom payment. The seller's Audiogon account was later discontinued by Audiogon for some other nonintegrous behaviour with another member.
All fees should be disclosed upfront. If the seller didn't mention the fee in his ad it should not be your responsibility.
I believe it's against PayPal terms of service for a seller to ask for pay pal fees.

Please explain what you mean by you had already made the payment.
