Maybe, you, our wonderful and brilliant readers, can figure out the logic behind the pricing scheme for aquarium air stones that Kevin discovered at Petsmart. Because we sure as heck can’t. In a move that would make Target weep with envy, air stones become more expensive the more you buy.

I was shopping for fish tank this this past week at the Pet Smart in north Seattle, and I came across some great prices for air stones, the little guys that make bubbles for your fish tank.

Always looking for the best deal, I saw the six pack for $3.99. Sitting right next door to the sixer was the single, at $.99, the econo pack was looking pretty good, coming in at just over $.66 each!

Then, lo and behold, one more peg to the left, were single stones, this time with no fancy packaging, at $.49 each. I think I’ve found a winner! Good thing these are sold individually, according to the bulk box, because those singles in nice packaging right next to them seem to be sold with a healthy dose of ripoff!
