Dude - I live down the street from a GF. My theater room is from GF. His first Astros promotion was $5k on any furniture. This year was only on mattresses. Maybe you should walk into one of his stores before you try to flame.

You do the math. He has 3 stores. Ain't no way in hell is he selling that many mattresses. Even if his markup was 100%, he's not selling that many mattresses. I spent several hours in his most popular store several months ago. He was not selling that much furniture let alone mattresses. I thought maybe he could be selling a shit load online, maybe folks in China was buying a shitload but you have to go into the store to get the promotion, so I call bullshit.
