So I have been looking for an Imperial Flagship (10210) for my own collection for a long time now. As I was browsing eBay I saw one pop up for a $145 buy it now plus $30 shipping. This was an awesome deal so I jumped on it right away. Well I just got a message from the buyer saying he made a mistake in the price and meant to list it higher. Do I try to hold him to that price? Or do I just let him do the refund and relist the item. He did say in his message that if he has no choice and I plan to give him negative feedback then he will ship it. I haven't responded yet and could use some advice. On one hand I really want this set. I have been screwed over on eBay plenty of times by other sellers and I don't want to be the nice guy any more. But on the other hand maybe he did make a mistake and I should let him off the hook. Any advice is appreciated.

Lesson to all to double check your asking price when selling on eBay. In this case, both parties honor their sides of the transaction. No more no less.
