I'll tell you how. I went in to buy some button batteries for my keychain flashlight. I needed 4, salesman said it would cost $20 bucks. I felt it was too expensive but bought it anyway, thinking they were a specialty item. That night I go on eBay and found out I could have had 4 for $5.
They sell basic crap and stuff for big margin. You open their flyers and see a huge ad for a alarm clock at $25. The only way they can justify the full glossy ad for stuff like that, is because the margins must be killer.
