My MIL brought me a few internet coupons she didn't use, I asked how she got so many for the same product. They are Bricks coupons and you can only print them twice per computer. Turns out she has been photocopying them!
The worst part, most of the ones she photocopied are ones I gave her that I printed from my computer because she has a hard time using her computer. Ugh, now I am all concerned that when these multiples get back to the company, they are going to block my IP address or something.
