If you don't plan on biding your time before playing Fallout 4, then this deal is about as good as it gets before release. Along with a copy of the game on your platform of choice, you'll also get a perk poster for your vault — all for $58.
The deal is up on eBay and comes via The Gamesmen. It's only a dollar cheaper than the likes of JB Hi-Fi, but if you haven't already got your copy sorted, this might be the time. The poster doesn't hurt, either.
Before you ask, yep, that includes delivery.
Now, for the catch. OK, not so much as a catch as a PSA — there are only 2000 copies available as part of the deal, with 554 purchased at the time of writing... though that might change quickly once word gets around.
