They may very well not be making a profit. But I have noticed that whenever I purchase parts or materials for my business at a too good to be true price... they are usually out of that product the next time I come back, and then say they don't plan on having more. Like mentioned already, that tells me that it was probably bought in a liquidation sale or something. And there are many businesses out there, that that's all they do. Witnessed by the slew of ebay and Amazon shops that have a bizarre collection of items that have no common theme.
