From the pictures, it looks as if they rented an old Ames or Hills department store. That's a whole lot of space to heat and cool and a lot to patrol for shoplifting.
The bit-off-more-than-they-can-chew syndrome is often a museum thing, but can affect retail. Somebody offers a deal on a huge space, the business takes them up on it, then they discover that their stock looks sparse on the miles of shelving and keeping everything clean and operating is a pain. Add the fad nature of R/C to the burden, and it's too much to handle. Betting on anything trendy takes incredibly good luck and timing.
