So I need to upgrade due to my form views, choose Silver and it wants to charge me more?

This morning, I have logged in to upgrade my account due to form views being over the limit. I'm on Bronze at the moment, so would need to upgrade to Silver. Clicked upgrade, selected the Yearly $319 (copy pasted at the top) and then it send me to another window to order, with a price of $440+ 

Why is there a price difference? What is the yearly price? 

The price may have been automatically converted by your payment processor from US dollars (USD) to Australian dollars (AUD). I would like to inform you that the price for the Silver Yearly plan is displayed in USD, so the Silver yearly will be shown as $319USD. However, since you are an australian user, the payment processor automatically converted the price into AUD, so now when you opened another window, the price will be shown as $440AUD or any rate at the time of your upgrade.

If you need further assistance, please let us know.
