One Sam's Club Member's Mark hot dog with a bun is 660 calories and brings 32 total grams of fat. The real kicker with hot dogs, of course, is sodium — of which the Sam's beef frank alone has 1,370 milligrams, plus an additional 280 in the bun, for a total of 1,650 milligrams of sodium.

Walmart, Sam's Club's parent company, is responsible for sourcing and manufacturing the Member's Mark products.

Sam's Club is the apparent wiener in its low-cost franks war against arch-rival Costco. The membership-only retail warehouse's decision last November to undercut Costco's $1.50 hot dog-and-soda combo with its $1.38 deal helped catapult Sam's Club ahead of the rival chain.

For just $1.38, the Sam's Club hot dog is definitely a great deal, but it doesn't compare to Costco's. Costco's hot dog is so impressive that it doesn't need them. It's great with nothing but ketchup.
