Never!!!! Fall for the free sample and just pay shipping, once they have your card details, they will charge it. I am also saying this about ANY!!! product that offers free sample or free shipping just pay for sample, have been scammed several times, I have learned my lesson, if I see a product that I want to try I will get the name check it out on Amazon and read the Amazon reviews, if I like what I read I will order from Amazon, that way I have no problems trying to return anything or being scammed Ever Again!!!!!! Why do I need to write at least a hundred words, I have said what I want to say..!!!!!!
