This may not help someone with a last second journey, but for the most part, there is no reason not to order the test kit a month out and then submit it.
There is always the risk that Fedex loses the package or whatever, but labs lose samples too. Only so much to be done.
As someone has pointed out to you in another thread, Hawaii requires the test to be observed so this mail in test in not acceptable for the purpose of this thread. Please stop spreading misinformation.
