Although we continually monitor inventory to ensure product availability, there are times when products may become temporarily out of stock or, in some cases, unexpectedly no longer available. We work closely with all our distributors to maintain accurate inventory and availability.If an item does become unavailable, we will call or email you to suggest comparable substitutions. In cases where a substitution is necessary, we will email/call you before shipping and provide the option to select other items. If you decide not to make a substitution, we will ship available items minus the out of stock item(s) or cancel/refund the order if you prefer to do so.
