If the seller didn’t ask for Paypal fees in the ad, then you’re under no obligation to pay them. If you paid half the fee...good for you, but you had no obligation to pay and the seller has no right to ask. That’s the simple answer!
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.
