Thanks, I would then be using the Walmart site for the return to local store and refund policies.There are some long running threads about Bangy bang tubes on Tube Asylum. Apparently not the most honest or honourable tube seller. I have not dealt with them myself.
I once ordered some whole house water filters thru Walmart, and read that for some people they were too tall. Turns out I too was one of the non-fit customers. I opened two of the filters out of the case to check fit but got a full refund on all.
