I have bought lots of cards from the Wentz brothers, directly or through their various eBay entities. They are one of the most knowledgeable sellers in the hobby. They have always responded to my questions, sent via regular email or through the eBay message system, in a timely and polite manner.
They are not bashful about asking high prices for premium quality cards. While there have been cards that we were not able to agree on price, they have always negotiated with me professionally.
There have been times when we settled on a price for a card that was listed on eBay, and I have offered to buy the card in a private sale so that they could save the fee. They always tell me it's no big deal and to just do the transaction on eBay. Also, they insist on sending my purchases Fedex overnight even though I usually tell them that there is no rush.
I mention this because I just cannot imagine that they would renege on a sale for $50.
