when was this? I have not heard from a customer for a long time that the shipment did not go thru, let alone 3 shipments.
you have to take into account that we changed our packaging drastically over the years. It used to say 'EZ Test for XTC and other drugs!!' on the front, and that did not help with bringing over a certain feeling of trust/confidence with customs. they nailed us for that a million times.;-(
after this has been changed to a more neutral way of packaging , I have not heard of many tests that did not arrive at their destination, except for the ones for which the customer gave us an incomplete address.
email me if you want to discuss this further.
