It’s no different than shipping costs - some include them, while others don’t. When I post an ad it includes any transaction fees. When a buyer offers and I am willing to do a counter offer, it usually includes the buyer paying any fees associated with the transaction as it changes the transaction completely.
If I have a product and offer it at an amazing deal, I usually list a bottom dollar number as what I want to pocket. It is then up to the seller to determine the proper payment and he/she can avoid fees by doing a check or other form of payment.
I do think people forget that when they buy a product at MSRP, shipping and transaction fees are included in that price. When it comes to resale, sellers normally don’t want to pay it as they only view it as eating into their sale potential. It’s always interesting how the shoe fits when its on the other foot.
