LFS would not take the 36" coralife back, so we will be using it for the time being.
Wow... they wouldn't take an unused (probably still in the box?) fixture back for credit?
I wouldn't feel too bad about buying hardware online instead of from them, if that's the way they're going to treat you. They've got to know you're at the beginning of a big $$ curve, and to not give you a break is pretty short sighted of them, in my opinion.
