I'm pretty sure you can get the difference back since it's winning 30 days.

30-Day Price Match Promise
If within 30 days of purchasing an item from a Fry's Electronics store you see a lower current price at a local authorized competitor in-stock, or from an authorized Internet competitor ready to ship, Fry's will cheerfully refund 110% of the difference. Or if within 30 days of purchase you see a lower current price from a local Fry's Electronics store, Fry's will refund 100% of the difference. To apply for Fry's price match promise, simply bring in your original cash register receipt and verifiable proof of a lower current price.
I didn't get it from Fry's unfortunately. While I could return it and repurchase, I have already used it, so I wouldn't feel right. Not to mention I would have to wait for it to get shipped (again), and I'm only part way through my project.
I waited forever for this thing to go on sale. I was pretty happy with the $85, which seemed like a few dollars off. If I had just waited a few more days....
