Someone's getting fucked in the end. As I previously mentioned, extreme couponing defies the intentions set by the grocery store and manufacturers standards. I understand manufacturers have overstock, but they're actually taking a hit when they don't make any profit off these goods. It's bad business.
I believe the grocery stores could give two fucks whether there are coupon users or not. Probably creates unnecessary overhead on them since they have to follow the manufacturers rules in order to be compensated for them.
What I don't get Einstein, is why you start an argument stating it is theft, but now its bad business? No shit, Sherlock. The manufacturers know what they are doing. If they want it to stop, stop printing the fucking coupons! Pretty simple really.
Again, you cannot fault crafty consumers. You have to think outside the box.
