It was on a whim that I even went. We were at the pharmacy near by, and I suggested going to petco cause I wanted to look at prices of tanks again. I needed to get my boys out of their smaller quarantine tanks and into permanent 40breeder tanks. I walked right past the sign that said dollar a gallon sale. Lol. Husband had to call me back. I got three of the 5 they had left!! Was 1/3 the price. Can't freaking beat that!! My boys will be so happy this weekend to be out of quarantine!!!
