My son and I were recently in Sam’s Club to pick up some batteries when I noticed something interesting… The 32-pack of Energizer AA batteries was selling for $10.66, whereas the 48-pack was selling for $16.66. That’s right… The larger package was actually slightly more expensive (on a per battery basis) than was the smaller package. While it wasn’t a big difference, this is the exact opposite of what one would expect to see. In fact, I was about to grab the 48-pack when I did a quick bit of math in my head and realized what they were up to. Guess which pack was featured prominently throughout the store, including big displays right by the cash registers? Yep, the marked up 48-packs were everywhere. In contrast, the marginally-more-economical 32-packs could only be found in the electronics section. The lesson here is to make to sure that you’re actually getting a better deal when you buy the Ã¼ber-pack of whatever you’re shopping for. You might just find that the smaller size is actually more economical.
