Sounds like they ran into what I'm theorizing, that there just isn't the population to support that many of the same stores, not enough to cover land lease or property tax, employee pay, suppliers, HVAC, utilities and to make a profit!
I don't mind the ones in my area so much because the local building codes (literally created by town residents in Town Meetings) tend to make them at least have a facade of Cape-style grey wood, 19th century brick or such, rather than the postmodern blandbox I see elsewhere. If they fail, they can be something else. It's not like a dead big-box, which tends to become an empty big-box forever.
I just wondered at the market oversaturation! Whether anyone else's area is becoming that. Hearing that some other places already have been there and done that, it makes me wonder why they seem to be repeating the pattern that didn't work elsewhere, here, all over again.
