Bought this mystery box for $20 at this years Las Vegas Comic Con. The only thing in this box was one old Nintendo game that on eBay tops out at less than $10. Any other mystery boxes I have bought elsewhere usually have either multiple items that equal the amount of the box or items that are at least worth more than spent.
I'm not sure where they got their value as the game has a price sticker that says $20 but on no sites have I found this game to be worth it.
Well I guess buying a mystery box is a gamble and I lost but there was a lesson learned I will steer clear of their stores (if $20 is what they are selling this for in the store then I can only imagine the price on something of worth) and their future booths.
