need to find a way to stop spending as much

I hate grocery shopping to being with but then I try to find ways to save money and it's hard. People say use coupons, buy what's on sale, and get the no name brand.

I try to use coupon but since I usually buy the no name brand it is cheaper that way the items I want aren't always on sale so then what?

It can be so frustrating trying to save money.
