This past August 6th, I was in one of my local Target stores (Craycroft and Broadway) in Tucson, Arizona. I snapped a picture of a “buy two and save” item that I thought you guys might like. The difference is only a five cents, but it’s still more expensive to buy the twin pack of deodorants instead of two.

From now on "buy 2 and save" really means, "pull out your calculator."

Reader Austyn, who found the deal at the Layton supercenter in Utah, adds:

Great to know if I go to Walmart I can "Buy 2 and Save!" a grand total of -32 cents.

This isn't the first time we've seen stores futz with unit pricing to screw careless consumers. If you see "Buy 2 And Save," slow down and look for the unit price.

Target: Buy 2 And Save! Sort of!

I'm hardly the first to point this out, but had to snap a few pics of the dryer sheets I was buying yesterday at Target.

Note these are regular price items (no sales/clearance). Buying the 120 ct box is a 32% price jump (per 100 sheets).

This is regarding something that has always bothered me. While grocery shopping today, I decided I'd better pick up some cat food. I always buy a case of the Fancy Feast 3-Flavor Variety Pack, sliced. That's the only stuff my cat will eat. I promise, I've tried everything else. So, I'm looking over my two choices, which are a 12 pack (4 of each flavor) for $8.29, or $3.684 per pound, and a 24 pack (8 of each flavor) for $17.65, or $3.92 per pound...

As usual, I become irritated because the larger box actually costs MORE than buying two of the smaller boxes. I would love to buy just one size large of the stuff, but the Purina company has made it impossible for a half-way intelligent person to do so. So, as usual, I buy two of the smaller boxes. Once at home, I decide I'd like to email the Fancy Feast people and inquire as to why this situation exists. So I sent them a little note that read: Shopping today, I noticed the 12 can size of the 3-Flavor Variety pack (sliced) costs less per pound than the 24 can size of the exact same product. I can buy two of the 12 can size boxes for about $1 LESS than I can buy one 24 can size. I think consumers naturally think that buying in larger quantities will save them money. I've noticed it has been this way for many, many months, so these are not products that are being discontinued, or are on sale, etc. Why would anyone purchase a 24 can box of your product when they can buy two 12 can sizes for $1 less. Can you please explain this pricing structure to me? It makes no sense. Thank you. So I guess we'll see what they say. Thanks for the work you do.

By paying attention to unit pricing, you've attained the next level of Consumer Ninja-ism. Congratulations!
