So... if they can look like the same IP address, they still must not be? Because I read here that some are able to print the same coupon twice from each computer, when the limit is two from each IP? (jealous LOL)
The limit is not done by IP. The coupon software keeps track on each computer.
Sometimes the cashiers just don't understand the entire concept of how coupons work. I had one cashier at Rite Aid that would just complain constantly as she was scanning my coupons about how I am ripping the company off getting all this free stuff.
