I bought this product for a friend, the offer was for AUS$4.19 the product arrived etc o.k but I have since been charged US$1.49 and then later US$39.95. These charges were not mentioned apart from them being dropped as part of a promotional offer, for which I had to enter a code. I want these extra charges reimbursed. I will return unopened bottle for full refund if needed. What a bloody ripoff!
