Someone correct my ignorance, but there just aren't coupons for what I normally buy, nor are there coupons for staple products. Trying to coupon makes me tired.
I can see why people do it, though. It's the bargain hunting part, the thrill of winning against your grocery and drug store costs. I do the same thing for thrift store shopping, where I'm willing to spend a bunch of time panning for that gold.
Some people like it, some don't. If you don't like the couponing or thrift store shopping itself, then it's not worth the effort. That's not true for the big stuff like housing and cars, but it can be true for the smaller stuff.
In this way, the original author, Kayla, has a good point.
