Canned Tuna Is Cheaper Elsewhere

Canned tuna is an inexpensive food that’s good for you, but buying it at the dollar store will cost you more than at Walmart.

At Dollar Tree, you can get a 5-ounce can of Van Kamp’s by Chicken of the Sea for $1. But you’ll pay just 90.5 cents per 5-ounce can if you buy a four-pack Chicken of the Sea for $3.62 at Walmart.
