If you are looking to purchase Covid tests for travel, please avoid this company. Despite choosing the next day delivery option, my test took over a week to arrive, making it completely unusable as I had already left the country and needed to purchase another test from a different provider. This would of course be understandable as delivery delays happen, especially around Christmas; however, customer service was very confusing and rude, with one employee initially offering a refund and another one backtracking and informing me that no refund was possible and that I can still use the test "in the future" (I will not be needing or using it at all). No solution at all was offered. Very disappointing.
