If you’re shopping for Right Guard deodorant at Walmart, be careful before you pick up that twin-pack thinking that, like the packaging says, you’ll “Buy 2 and Save.” Because if you do the math, you’ll realize you’ve just saved yourself out of $.97.

Eagle-eyed Consumerist reader Chad spotted this at his local Walmart and noticed that the $5.97 price for the twin-pack was noticeably more than twice the $2.50 price of the same product sold individually.

By comparison, this makes the $0 savings at last week’s Old Navy sale look reasonable.
