If any of our products show "expiration" dates, these are indicated primarily for retail purposes. This shelf-life period is for the benefit of wholesalers to determine how long they can keep items on display or in stock. Many of our products last much longer. And beyond their "good-by" period, they do not "rot" or "go bad" (they're not food). These products are a-ok for use (if not for store stocking) and cannot be returned or exchanged.
