If a warranty claim is submitted on a product that is no longer being manufactured and we do not have any inventory available of that product on-hand, we reserve the right to substitute the replacement for a product comparable to the original in value and quality. If a substitution is necessary, we will advise you of such. We strive to make the best possible selection based on your original purchase. If we determine that we do not currently have a replacement that is comparable in both value and quality, we will upgrade the replacement at no cost to you.
