They always seemed to be getting in more and more merchandise, despite supposedly closing down. Google Streetview's old images form May of last year even have that same blowout sale sign.
And oddly, they're one of the businesses where Google Street View actually took their cameras inside so you can browse around inside the store from Google Maps. Previously I found interior shots of the Red Derby, Red Rocks and Looking Glass Lounge on Streetview, which are really fun to explore.
But anyway, it seems they have finally actually closed -- or at least changed names. The shop has the "Brown's" part peeled off and has new signs that say Casa Furniture, plus signs in Spanish saying they're hiring. I guess better a kooky furniture store than another cell phone shop.
