Not Using Discounted Gift Cards
Another way to score easy discounts on groceries is to use discounted gift cards. You can find supermarket gift cards selling for less than face value online. You can use a site such as Gift Card Granny to find which gift card reseller is offering the best discount on the card you want.
The savings might not always be dramatic, but it’s a relatively easy way to save money at the supermarket checkout.
Assuming Bigger Is Always Cheaper
Buying items in bulk can help you save money. But you shouldn’t always assume that the biggest package is the best deal, Nelson said. For example, you might find that the sale-priced, smaller size has a lower unit cost than the largest size. Check the unit price before you buy it.
