Well to be fair, the Fry's deal was very limited and not eligible for shipping and the one being offered by MacSales is a used unit. You must be in Washington state? As of right now, the only Fry's that has the MC184LL/B keyboard listed for sale in any form is in Renton, WA. It's also uncertain as to whether they really have special items in stock. I've had and heard of others having mixed results with going to redeem an insanely good deal only to be told when they got there that they couldn't find the item in the store.
I've found one other MassDrop item going for a drastically lower price at Fry's, but under the same conditions. It was only available for direct pick-up and only three locations had it. Someone here tried to go get the item and was told they didn't have any.
Anyway, I just picked up a brand new and sealed MC184LL/B off of an eBay seller for $30. That seems to be a pretty good deal for one that's new-in-box and sealed, but it's pretty easy to find something for around $30 that's used and in excellent condition.
I'm normally a bit of a mechanical keyboard snob, but I'm very fond of this particular Apple keyboard and I now have three of them. Two are stowed away as backups just in case these become harder to come by in the future.
I have a new 2016 MBP with touchbar and I often use this instead of the built in keyboard. I'm ok with the new MBP keyboard and actually like it better than most recent MBP keyboards, but still prefer the Apple Bluetooth Keyboard for extended typing if I'm away from my desk. One nice thing about the touchbar and the flatter keys of the new MBP is that they form the perfect groove to allow you to drop one of these Bluetooth Keyboards right on top without it slipping down during use. You lose a bit of the touchpad, but not enough for it to be a serious hinderance. On my old mid-2012 unibody MBP, I had to tack on foam strips to my MBP to keep the keyboard from sliding down during use.
