This kit was 1/3 the price of other ones and included the testing. It was very simple to do. Waiting for the results right now. We are looking to sell and want to get all this stuff out of the way.
This was one of the cheapest test kits I've found. The lab analysis fees are included, you just have to put 5 regular stamps on the envelope that's included. They emailed me the results, which made it fast. You can get them via regular mail if you prefer. No problems, no surprises.
