The covid tests had a use by date of 2 weeks after purchase. Seller was not sympathetic and refused to refund saying most people use them straightaway. I only needed 1 to confirm negative after being positive for 6 days so the other 4 would have gone out of date. I sent someone to get one from the chemist so now i have these 5 tests that are going out of date in 3 days time! Avoid this seller
