Expiration Date Guidelines
To determine how many months are left until your supplies expire, count the current month as “0” and the next month as “1” and so forth. For example, if the current month is January (month 0), and your test strips expire in August, we would consider the test strips as being seven months before expiration.
This is how we count when figuring out your payment. We are able to pay the most for diabetic supplies that are furthest from expiring. Expiration dates and payments are explained on our Sell Your Strips page. If you have any questions, don’t hesitate to call us at 855 578 7477.
