Groceries make the biggest part of the average family budget and when you have an opportunity to save on such purchases, you can save a lot. There are a lot of tips and pieces of advice about how to save money while shopping in grocery stores, but most of them have one thing in common - they recommend using a rewards credit card, a cash back card in particular.

An average cash back credit card can save you at least 1% on purchases. That not much, but still better than nothing. The most popular cash back credit cards are Discover cards. Discover is well known for its cash back offers and its best credit cards offer up to 5% cash back in specific shopping categories. For example, Discover it® Cash Back allows to earn 1% cash back on all purchases and 5% cash back in rotating categories on up to $1,500 in purchases when you activate. Note that you need to register each decade to start getting rewards within the category.

Other credit card offers you will like are credit cards that offer cash back rewards on groceries. Grocery purchases usually get a higher reward rate on such cards. You can get extra money for every trip to a grocery store. Just make sure you pay off the card balance every month to get the most out of the card.

Store cards can also help you save on shopping. Many grocery stores have loyalty cards that give access to additional discounts or sales events.

There is a wide choice of rewards credit cards that can help you save on groceries and other purchases. Just make sure you choose the card that is good for your credit and the rewards program suits your shopping habits.
