I added the Domain Auction membership to my account and the price went up. Seems like it's trying to scam more money from me than what it is actually priced at. In my cart it's priced at AU$8.79 but the page displays as below (note price of AU$6.47):

Sorry, I should have mentioned it - the tax and fees is already AU$0.80 in the cart. Which is 10% of $7.99 - it still doesn't work out. Thanks for your reply, again sorry - I should have stated that in my original post.
