I've been trying and trying to save money on groceries. I know the best way to get better deals is to use coupons when the items are on sale, but for instance, this week, the items I need are not on sale but I do have coupons for them. So which is better, to shop based on the store flyer that comes out weekly and hope you have the coupons to go with what's on sale or is it better to shop based on the coupons you have on hand?
