Grocery stores spend a lot money to research ways to get you to put extra food in your grocery cart. Don't let them outsmart you. Stick to your grocery plan.
Sales run in cycles so stock up enough to last until the item goes back on sale.
I Keep a Notebook in my purse with the grocery stores listed and the sale items under the name. I also put the sale price in parentheses. I pulled my list out the other day to tell my niece who had mayo on sale and how much it cost.
I want to save on items that can be used, and I want a well stocked pantry. Honestly, who has room for all that stuff? If I see a good coupon online I can't resist, I will print it. Most of my coupons come in the food I buy or something that comes in the mail. I don't have time to run down coupons. If I have them, they are an added bonus.
Stocking up is the secret to saving on groceries. Don't buy anything unless it is on sale.
Plan your grocery list with sale items and plan your menu around the food in your pantry and freezer.
