A wise lady once told me you should always use coupons in grocery markets. No matter what the markdowns in the grocery markets, the people who own the store always make a profit so don't feel embarrassed about saving yourself some money. I am more bold now than I was several years back. There are some things I will use a coupon on, but food, I just cannot grin and bear giving the checkout folks a coupon on the purchase made in a restaurant. I'm working on this silliness of mine.
We always stockpile on paper products, but a year's worth of product is a bit much

Perhaps 2 months' worth at most. Sam's Club and BJ Warehouse work really well at giving you the most with your money. As long as the products which are on sale will be utilized by your family, you might as well stock up while the prices hang low.
No guilty feelings here!! It is a worthwhile cause!
