销售：二换一

We don't know about you, but we love it when we find something on sale or for a bargain. Like how, when you go to the hardware store to buy a box of nails and they might have a sign out that says, 'Buy One, Get One Free.' Don't you love that? Well, imagine that you set out to get yourself some pussy and when you are about to make your purchase, said pussy tells you that you can get a whole other pussy with this deal for the same price.
