When you take a test for employment the test results become property of the company and you are not allowed to have the results. This is why companies offer this refund. Also depending on what state you are in, it may be illegal to sell anything that could be used to falsify a government or employment drug test. The laws were past in the last few years and are in places like Arkanssass, New Jersey, North & South Carolina, Pennsylvania, New York, Texas and a few other places. THis would keep them from admiting that it was even created for this, thus negating the refund. A sure fire way to pass is to get a colostomy bag from a med supply store and get someone else to pee for you. You can get the bag from a med store for about $20-30 or buy a kit on ebay for about $15 with a hose and heating pad. The web sites that sell urine are sometimes even worse. Mostly they sollicit urine from people and never test it before it is sent out. The money they make can cover a few failed tests and they can get new samples before sending out new orders....so it just screws a few people (a real gamble). Their money back guarantee is the same way. If you pay with credit card you can order, either order priority to avoud signature confirmation or do not sign or sign a different name, then file for a charge back through the credit card company. This way you get the product for free so if it fails, you dont loose anything. Ive never done it myself but if your sick of getting screwed its an option. Its good for one or two times after too many times you need to be careful the credit card company will recognize a pattern for fraud. Hope this helps someone.
