The expiry date is mentioned on each blister. It is different for different batches. The shelf life is 2 years from the date of manufacture and would differ from batch to batch depending on when they were manufactured.
I appreciate your personalized customer service and prompt follow up. All I can say is this, if you are this straight forward and direct when something goes wrong, then you treat your customers with respect. And if you do that on a regular basis, you deserve to have great things happen to you in the future.
I will be in touch.
