ONGO Returns Policy
Due to health and safety concerns, COVID-19 Antigen Self-Tests cannot be returned even if unopened and no refunds will be issued. Accordingly, all sales of COVID-19 tests are final.
PLEASE NOTE EXPIRATION DATES BEFORE PURCHASING. Currently, the test expires on the last date of the month printed on your box (i.e. January 2022 means January 31, 2022). However, with medical products under EUA, such as On/Go, the FDA, after close studies, grants rolling expiration extensions. We expect the expiration date to be extended before the end of January and another expiration extension again early in spring. We will continue to closely update our website when the expiration date gets extended.
DemeTECH reserves the right to remedy customer issues and concerns on a case by case basis based on the facts and circumstances of each customer.
