That's why I throw away nearly all manufacturers' coupons.
Even with the coupons, name brands are nearly always far more expensive than store brand.
Except for a very few items, I've found them to be otherwise identical.
I've noticed that too; that's why I'm not enamoured of the things.
For example, one might see a "40 cents off" coupon for a Kraft product.
Okay, forty cents isn't chicken feed, and so one checks it out.
Well, the Kraft product is $1.79, while the store brand is $1.29.....and the coupon doesn't cover that difference.
