I ordered Wuyi-Tea at https://www.wu-yisource.com/. The Free Trial advertisement states "You only pay a small fee of $4.95 for shipping". The product made me sick and due to travel I was not able to return the product and cancel future orders until approximately one month later. In the meantime Wu-yi charged my credit card:

2 x 59.95, 2 x 4.95 web access, 1 x 9.95 membership, 1 x 2.00 and 1 x 2.95 for a total of $144.70. I have the credit card bill to prove it. So how did $4.95 turn into $144.70 in a month's time? Fortunately I disputed the charges with my credit card company and all but $5.00 was dropped. And don't type in your phone # when you order - they call you constantly! BIG MISTAKE!
