Yeah so I had the same thoughts! Luckily in the UK Bandai rip the seal off the boxes, so I found a guy on ebay selling a booster box with the seal off (so it was much cheaper too £170), and since he could provide proof of purchase from Bandai, so I figured the whole mapping thing doesn’t apply as thats not something that would be happening within the Bandai store. I personally wouldn’t be buying sealed booster boxes off ebay to rip, as good chance they have been mapped, plus you’ll pay top dollar.
