So this morning my fiance came and told me the following :
" I don't know why I'm telling you this but Petco is having a $1 per gallon sale."
Me: " Yeah I heard "something" about that.
They'll make up all the money they lose on the tank through sales on fixtures and supplies.
Her: " Makes sense. Wasn't sure if you knew about it or not."
Me: " Wasn't sure if it was factual or not but, I guess, this answers that question."
Now....she hasn't seen the 75 gallon tank in the detached garage yet, but this certainly sounds like a green light conversation to go and get another tank.
disclaimer: she did say a tank in the bedroom would be nice if I took care of it, although I do take care of my other two tanks.
I figure the worst thing is that I'd sit on it for a while. ( not literally)
