Thanks!

It sounds from your post, this is someone worth maintaining a strong relationship with. I'd suggest some measure of recompense. I would certainly not give back the card, or make any trade that puts you negative overall. Fact of the matter is the deal was made given the knowledge available at the time and no one is at fault. However, on the follow-up trade offer an extra throw-in. I'd say of extra value equal to half of what you gained on the first one. This closes the gap to something easier to swallow without having wasted your time.

Basically it sends the message, I didn't mean to screw you and I feel kinda bad about it, I want to make it up to you, but this was your mistake too, I didn't force you to make the trade.

Keeping strong relationships with your clients is important, but letting them walk all over you can have far worse repercussions then letting them walk away.

Looking forward to hearing how decide to move forward.

The fact that some people think they can act this way without any repercussions is appalling.

He felt angry, not because you deceived him, but because he thinks it’s wrong to trade for value. If you don’t agree with him, stand up for yourself. You were honest and he consented. We’re all adults here.

It’s not your trading reputation that takes a hit in this exchange; it’s his. His reputation now reads: “I want a takeback clause in my trades and I’ll cry foul if I decide later that I don’t like the trade.”

Your relationship with him will best be repaired through future honest trades, not by giving him appeasing gifts you don’t think he deserves.

A) $8 vs $5 vs $3 isn't a massive ripoff. It's a question of a few bucks. The fact that you owned up to the mistake should have been enough.

B) When someone apologises to you for making a mistake, just accept the apology and get on with your life. This guy is sitting around holding a grudge, all butt-hurt, about a friggin' tombstalker.

C) Refusing to trade with you then waving a card you need in your face is bush league. Don't bother trading with this idiot.

If he had gripes about your previous trade, the time to seek a correction on it was the next time he saw you. He was in a strong position as it was the first chance he had to express his displeasure of the trade and the first chance you had to explain yourself. The correct thing to do if you wanted to do right by the guy was to make another trade slightly in his favor.

But he passed on that opportunity and seemed like he wanted to be bitter about it instead. At that point I feel he surrendered his claim to have grievances redressed.

Either you fix it or go home and sulk. He chose option 2.

Anyway, then trade as normal for the Kira and watch him give youb a great deal on it for being cool. Probably enough to make up your loss. Or if he just takes it and walks off, at least your karma is repaired. Karma will follow you to the next trade as well.

Set it free. If what you’re saying is true, you just wanted a throw-in and he handed you a meal ticket. Correct his mistake, humbly take the loss on the original trade, and the good will you just purchased will pay off in tangible and intangible ways.

Plus if others see him refuse to trade with you, that can hurt your reputation too. Don't look at the couple bucks throw-in as a loss, but rather an investment. But I'd reiterate your position, which he's more likely to accept once he's been bribed back into line.

I know you don't want to do this every time you come out ahead on a trade, but I can't imagine this sort of thing happening often 😀
