I have actually had a harder time using coupons in past few years because of extreme couponers. I can't get the stupid coupons! My DH gets the coupons that get left behind from the papers people read on sunday, but I never get my circulars with coupons anymore and buying a paper is iffy is you use a machine because someone will buy one paper and while the door is open steal all of the coupons from the rest.
That being said, when I coupon, I coupon. I usually collect coupons from the stacks that DH brings me from work, the ones I get in the mail, the ones my relatives give me (they just shove them all in a bag and give it to me, I clip the ones I want and pass them on). When the perfect sale comes along, I do get things for free or nearly free. Detergent for between $1 - $1.50 a bottle, toothbrushes for a dime, frozen veggies for free, lotion, shampoo, conditioner for nearly free. I fortunately have room to store things, and when I can get things that I don't need, the local food bank will take them. I gave them almost a case of deodorant, 100 toothbrushes, and a case of shampoo/conditioner that I paid less than $20 for.
Cheapness - Was in a coffee shop with DH using a groupon on Saturday. Our total after coupon came to $3. I tip on the original amount and service was awesome, so I threw in a little extra. The couple behind and to the side of us was using the same deal. They milked it for all it was worth, stole an entire container of raw sugar packets, a whole packs worth a napkins, argued over the total, and left a .50 tip. Wow. I can see now why there are less and less groupons for restaurants in my area.
