Extreme Couponing gone too far?

So I must say I love to go to the store and get something for free, but are these extreme couponers taking it too far? I was amazed as I watch the shows where people get a thousand dollars of groceries for ten dollars or less but I feel that these shows maybe be helping retailers to change coupon policies so that the deals are not so sweet anymore. I also noticed while watching these show that these people are getting hundreds of items such as pain relievers, or antacids while on their shopping sprees. Is it really necessary to have that big of a stockpile of items such as those? Items such as bath tissue, laundry detergent, dish detergent,toothpaste and tooth brushes seem to make a little more sense to get massive piles of then medicine. Anyone will agree that toiletries and cleaning items can get rather expensive and are things a family can go through very quickly. I love to stock up on these items, but really I think its silly to buy crazy amounts of medicine, actually I think its a total waste. What do you think? Is it totally ridiculous to buy a hundred boxes of pain reliever? If you like to coupon what is your favorite item to get for free?
