Yes, read the rest of the ad. There are terms and conditions not disclosed.
Besides that, it's up for auction, so the price shown today could increase as it gets to the end of the auction. In the terms and conditions, it says he will take $2500. on "buy it now". I don't think that complies with Ebay rules. They may take it down. I could be wrong, though. I've not sold many items on Ebay and do not know all the rules.
