One of the things we promised you is to make testing accessible to everyone. As ever, we are doing our best to maintain a healthy inventory for our online orders.
However, we are facing significant increases in raw material costs. At the same time, the increased demand for testing does not allow us to reduce the air freight and labor costs.
With that being said, we must unfortunately raise the price of iHealth COVID-19 Antigen Rapid Test to $19.80 per pack with free shipping, effective Jan 11, 2022.
We greatly appreciate your business and hope you will understand the necessity for this price increase.
