I really like that the test is for both the flu and covid. However, I don't like that these tests expire on May 4, 2025, less than three months from the time I ordered them. I hoped to keep them on hand for when they are needed but they will expire soon. Repeated attempts to initiate a return have been unsuccessful. Walmart keeps referring me to the merchant (which I didn't realize was NOT Walmart) but the merchant doesn't contact me about the return. So I am dead in the water until the merchant contacts me.
