To be fair, that price is not all that practical seeing how people still need to pay for the shipping on the item, and the game itself weighs 12.2 ounces, and unless you want them to ship it to you in a bubble mailer, or a plastic bag, you'd have to account for shipping too.
This will only slightly make sense for those who pre-ordered it from BB, and got it 20% off with GCU, so maybe they'd be making a little profit, but your offer of $88 is ridiculous considering you have not even accounted for shipping cost (of course if you did want to pay for shipping costs, you should probably make that specific in your post somewhere so people don't think you are just being stupid).
Hope you find someone willing to part with theirs, but as your offer stands, people who have the game can just return it to get the same amount back, so what's the point of selling it to you?
There has to be some more incentive other than "Oh, just sell to me because that's the retail cost."
I mean you have to at least try to give us something more than a sob story, and maybe use some niceities, or say you will be grateful, or something.
There is just no monetary, or moral incentive here at all, so I am not surprised you received the response that you did.
Good luck with your search for a FESE, but I would recommend maybe retooling the strategy you are using to acquire one.
