You mean you didn't know??? Anyway, check this out, a guy trying to sell a walmart bike with a nice $30 mark up from list price of $70. I see this all the time and I can't stand it - I know it is unlikely, but what if some poor soul bought it thinking it was a bike instead of the bike-shaped object it actually is??
