SAN ANTONIO -

One of the easiest ways to save money at the grocery store is to buy store brands. But how do they taste?

Consumer Reports taste-tested 57 store brand foods, including frozen shrimp, shredded shredded mozzarella and vanilla ice cream. 

They bought the private labels at Costco, Sam's Club, Walmart, Target, Kmart, Target, Trader Joe's and Whole Foods.

Of the 57 tasted, 33 were as good or better, although not necessarily identical in taste.

However, Target's Market Pantry ketchup did taste similar to Heinz. The mayo from Whole Foods, Target, Costco and Walmart, while different from Hellman's, was just as good.

As for nuts, testers said all of the store brands were better than Emeralds.

If you're a big Breyer's Ice Cream fan, Walmart's Great Value vanilla came pretty close, and it costs one-third less.

"Buying store brands can save you a small fortune, anywhere from 15 to 30 percent on average, depending on the category," said Consumer Reports' Todd Marks.

Consumer Reports did not test HEB products. 

However, in a small test comparing HEB American Cheese Singles to Kraft and comparing HEB ketchup to Heinz, the HEB products were considered as good or better in four out of five tests. 

And, they cost about 30 percent less.
