They do it every summer. So lets say you buy a 55 gallon aquarium its only $55. Every aquarium is $1 for each gallon. Pretty good deal if your in the market for a glass aquarium. They can get expensive.
yep. sometimes they will only allow up to a certain gallon though. Its been a while since I went to a petco, several years actually. But still pretty cool deal.
Corporate has decided to start having it more often because it draws so much business. For the past few months we have been switching off between having reptile terrariums that are sold with the lids being half off to doing the dollar per gallon sale. Right now the terrariums are half off so I assume we will be doing the dollar per gallon sale some time in the next few months.
