Quick tips: How to save on your grocery bill

Grocery shopping doesn't have to break the bank when you use the right strategies. Here are three quick tips for reducing food expenses:

  • Buy store brands instead of name brands whenever possible.
  • Always make sure to compare unit prices, not just sticker prices.
  • Join your store's loyalty program so you don’t miss out on member discounts.

Even though something like choosing coupons in your grocery store app can feel like an annoying task, the savings can really add up.

Bottom line

Check your local Costco for plenty of main dishes, but don't forget the side dishes, which you can also stock up in your fridge for an easy bite.

Plus, remember that you can make the most of your Costco shopping trips — save extra money on side dishes — when you have the best cashback credit cards in your wallet.
