Besides, this is America not France, it is a huge bazaar where customer is always right. Think about it.
The "customer is always right" is good policy when you’re making at least 40% margin on each widget sold, there’s incentive for repeat business (more widgets to sell), and your customers have some grip on being rational & reasonable adults.
This was a PRIVATE SALE, peer-to-peer between 2 hobbyists, where in most cases the basis cost is equal to or higher than their sale price (net loss). As a buyer, I approach sellers with the utmost respect for their time. As a seller, I’m happy to help hobbyists who "operate" like me, and will quickly shut off those who don’t. Not worth the effort.
I’m pissed off on behalf of the seller, too. We’ve had countless threads on Audiogon where an OP will complain about some malady / slight and yet still RESUSE to name the manufacturer or dealer. Yet here, seller was clearly a good guy, and OP came right out guns blazing to try and "name & shame"? Wtf?! Anyways, there’s no point trying to convince folks who are (bafflingly) on the other side of this. "No soup for you" policy applies, as needed :) Go find your gear from a less scrupulous seller, or pay MSRP from a dealer who will entertain some silliness for profit.
