It is sad... I've bought a lot of toys from TRU in America, and would feel worse if botcon was still happening. TRU was always a priority, with Walmart And Target when I was in America, and it would be a factor in deciding hotels when not at the convention. There is even one near the LA Airport that I had checked out several times before or after a flight, and once between two connecting flights (taxi there and back, with the driver waiting for me).
I think we'll miss the exclusives most though. There might not have been a lot, or cheap, but it was the store with the most despite Walmart and Amazon being bigger.
