This one works with a catch, due to high demand they say that “Please expect 1-2 months for your sample to arrive.”
They claim that “Due to overwhelming demand, your name and information will be placed on a waiting list to receive your free sample.”
If you don’t mind waiting, then click “GET SAMPLE” button below. However, most samples take about this long to be shipped and delivered just FYI. Hard to complain when it is FREE!
