I get the paper every Saturday(in Atlanta they sell the Sunday paper on Saturdays too). I also look online at the grocery stores websites, and I am a member of the grocery stores saver club. You have to look through everything in the newspaper because there will be coupons in the places you don't look. Also my store sends me coupons every couple of months based on items I buy regularly, which helps a lot. Also some stores double coupons up to a certain amount,( usually up to 50 cents) so you make sure to ask the cashier to double the coupons that can be doubled( it would be nice to already have it separated for them). Buy only what is on sale(if you like those items), and try to find the items on your coupons. Make sure you leave the children at home so you can shop wisely. It takes time, so you will gradually get good at it. I bought two weeks worth of groceries for about $90 yesterday. Be careful because some stores don't accept online coupons. But also check out websites for your favorite items. They often send out coupons to you as well.
Go to coupons.com, and also thegrocerygame.com..don't sign up for membership, but just click on free coupons link to the left corner. Also try coolsavings.com, and eversave.com. Not sure which grocery stores are around you. But here it is Kroger so go to your grocery stores website and check too.
