I didn’t exactly imagine them being a demographic big into a big box furniture and interior decoration store. Ikea, maybe.
Not even furniture, really. It's more like sheet sets, comforters, bed skirts, faddish kitchen utensils, small cheap appliances, towels, toothbrush racks, etc.
I expect a lot of BBBY nuts are the "mattress on the floor with no fitted sheet" type, but they probably spend money on desk/chair and living room media furniture.
For all the talk about "sticking it to Wall Street", it's quite likely that most of the biggest "winners" in the GameStop mess were Wall Street types. Either trading for their employers or trading in their personal accounts.
