We used On-Point yesterday and it was great.
I booked the two tests on Tuesday for my parents to cruise. I felt that maybe I made an error and the wrong email populated the screen, so called the toll free number. In about 5 minutes, a young woman answered and emailed me a new link so I could fix the email. It was wonderful.
I did take a screen shot of the order #
I also took a screen shot of the code for each person
You will need to confirm these with the person on the zoom call.
Then, yesterday, we used the free government BinaxNow tests. Had never used these and the young woman on the Zoom call instructed us clearly how to use the tests. Binax uses a card and not a vial/bottle.
As we hung up, I received a text - we were off to the market, but as soon as we were back home, the email was there with both PDF's. I downloaded, took a screen shot and printed.
Great job for $14.99 - didn't have to drive anywhere and customer support was fantastic.
Hope this helps anyone else.
