Grocery discounting has three separate layers and they stack on the same item. The store's own sale price comes first, a manufacturer coupon comes off on top of it, and a receipt-scan rebate pays you back afterwards. Most people use one layer and assume that is all there is.
The order matters. Load the store app's digital coupons before you shop, because most chains will not apply them retroactively once the receipt prints. Clip everything plausible even if you are unsure: unused digital coupons cost nothing and cannot be double-counted. Then check a flyer aggregator for the week's loss leaders, which are the front-page items priced at or below cost to get you through the door; buying those and skipping the rest of the aisle is the whole trick.
Rebate apps work after the fact, so they are the layer you can still use once you are home with the receipt. Scan before the app's deadline, usually a week. Two habits that beat coupons entirely: compare the unit price on the shelf label rather than the sticker price, and ask about a rain check when a sale item is out of stock, which holds the sale price for you until it is back.
Coupon doubling has largely disappeared and per-transaction limits are common, so read the store's coupon policy once - most chains publish it - rather than discovering the rules at the register.

How to play it
Two minutes in the parking lot; discounts apply automatically at the register.
One item can legally take all three: the store's sale, a manufacturer coupon, and a receipt-scan rebate.
Paper coupons skew toward staples and household goods; grandma's method still clears 5-15% for planners.
The front-page flyer items are priced at or below cost to pull you in. Take the bait, skip the trap.
