Wish complaint: Deceiving when ordering

My daughter and I were shopping for a few tops and saw a couple she liked. As they were in US$ the only way we could see what it would cost in A$ was to click the buy button. After we saw the price we clicked back out of it. We looked at 3 different tops and decided to order 1. When I saw the revised order it showed an amount (I can’t remember the exact price but it was around A$26 including postage.) When I went to check my emails I discovered that we had ordered all 3 tops. This did not show on the original order, only on the order which was sent by email. Your ordering process is DECEPTIONAL. We can’t afford to buy all 3 tops. The 3 tops came to a total of $86. A lot more than the original $26. The order is apparently on its way so it looks like I’ve paid the $86 but am not happy with your ordering process. I promise I will never use this site again and will make sure I tell my friends as well. SHAME SHAME SHAME. You’ve lost me as a continuing customer.
