My friends sister is a hardcore coupon person... The deals she can get out of them is unreal.

...However, when at the casino I watched her lose $500, after setting an initial budget of $50.

I'm the same as you with my coupons. The only incentive I remember to take advantage of is Stop&Shop gas points, now that Shell accepts them.

Extreme, I'm not, but I definitely clip when I can. It all adds up.

I used to be a hardcore couponer but that was when 1) they'd regularly double the coupons, and 2) the prices of things weren't so high that 20-cents off (which became 40-cents) actually mattered. I also used to pair the grocery store coupons with the manufacturers' coupons and with sales. Now the grocery stores won't allow this. And every other coupon I see says "do not double" on it. I'll still use coupons that are $1-off or greater, especially the wholesale club coupons.

Also, I got lots pickier about the things I'll buy (in terms of nutrition), and so many coupons are for junkfood.

I wouldn't call myself an extreme couponer, but I do use a lot of coupons. Between sales, store coupons, manufacture's coupons and the Walgrees and CVS deals, I pay very, very little for most personal care products (hair care, toothpaste, soap, deoderant, etc). It takes a bit of doing, but I save a lot of money and get to use good products.
For food, I don't use as many coupons. Mostly because I eat a lot of fresh fruit and vegetables (no coupons) or find that the store brands are an acceptable quality and cheaper than the name brand. That, and I've got an Aldi nearby. But I use food coupons when I can.

I Groupon, but rarely coupon. But I do have a great coupon story. Years ago a local supermarket chain sponsored a weekend event at the Civic Center where their vendors had booths with samples and coupons. It was a fun event with cooking demos, games, etc. On the weekend of the event, the stores offered double value on the coupons. Many of the coupons were very good, some for half the value of the item. For example, they gave out a .50 coupon for a .99 can of Progresso soup, which meant it was free if you shopped that weekend. I gathered up a bumper crop of coupons, went to the store and filled two carts. The cash register initially rung up $144.39. Then they took off the coupons and the final bill was $12.41. Everyone around me was stunned. One guy asked me to marry him. I was really poor at the time and that $12 filled my pantry for months. I held onto that cash register tape for a long time as a souvenir.

I'm almost positive @kamikazeken is into the Coupin'.

How to I know this? At the beginning of the year, when Portal 2 came out we were having a discussion over the legitimacy of a coupon and talking about bar codes. He shared his couponing wisdom.

How/why do I remember this kind of crap? Dunno. Also, this could all be a totally fake memory created by the matrix (and/or drugs, but probably the matrix.).
