I cut coupons for things I use. They don't have long expiration dates these days and usually expire before I get to use them but when I run out of something, or if there's a good sale on something I use anyway, then I'll use them but I don't get caught up on using them just because I have them. I don't usually have more than 10 or 15 in an envelope at a time. Also, before I go shopping I look on line to see if there are any coupons for things on my list.
As for things other than groceries, it's the same thing. I save coupons for things I usually buy but don't buy just because I have them. I use them if I'm buying that thing anyway, not because I have a coupon burning a hole in my pocket.
I also don't like to use digital coupons because I usually forgot what I added, or forgot to add, so I don't bother.
