Greentea Purity offers a free trial, with the cost of postage at $5.95. However after a few days, I received an email which stated since I had not contacted them after 15 days and had not returned the remaining contents, they were going to debit my credit card account by $79.95. The statement would record PURE - G - HEALTH. Not sure if that is the trading name of the company. I have reported it to the Australian authorities - ACCC.
