Reliance is not a factor in a breach of contract case. You make a contract; the other party breaches it; you are entitled to sue to get the benefit of the bargain you made. So what is the reliance factor you are bringing up? The key issue is whether they did, in fact, enter into a contract. But if that is in fact what they did, and the seller breached, the OP is entitled to seek the benefit of his bargain.He'd have to show reliance to get that amount. That may be hard in something as loosygoosy as ebay purchases.
If you are bothered here by some sense that it's unfair to the seller, I don't see it that way. The seller had the opportunity to do the research to find out what he had before agreeing to the deal. He didn't, and thought the deal was a good one when he made it. Once he agreed to the deal, he shouldn't be allowed to back out upon finding out he could have got a lot more. We hear about examples of this sort of thing all the time — like people who buy something for $1 at a garage sale that turns out to be worth thousands. Does the garage sale seller get to rescind the sale when that comes to light later? No. He made the deal, was happy with it at the time, and the fact that it turned out not to be a good deal for him is just the way the ball bounces; he could have investigated what he had and then not made that mistake.
