I have ordered COVID19 antigen tests from Sunline in bulk for our company and have been very satisfied. The orders came in a timely basis, especially in January 2022 (my first order with Sunline) when there seemed to be a shortage and then recently. I have continued to order and have been completely satisfied each and every time! If you need to order in bulk - use SUNLINE!
