I was at Walmart today for some cat litter and a few other items. I decided to get some orange juice. They had bottles on sale for $3, which is a common price there. Then, they had two of those bottles shrink-wrapped together, and you'd think the price was to be cheaper because you were buying 2 instead of just one. It was $6.28 for the two pack. I've seen the same thing there with toothpaste, paying more for a multi-pack than just one single tube. Anyone notice these things going on in your local stores?
