Tractor supply told me that they only do exchanges and you either have to buy your first tank or fine the same brand tank that they use so you might want to double check the brand. I ended up going with one from Delille as well. If you call them, they'll tell you who they deal with in your area. Dan I don't know if you take yours in but the store on 310 and Broad (can't think of the name True Value?) exchanges for Delille.
