I logged into my billing support to see how much I am paying per month, but it just says 1 Month Sub. I am guessing it is 7.95 CAD? It doesn't say anywhere, or at least not in an obvious location.
There are two ways to check:
1. check your bank statement for the last payment amount
2. log into account management and click as though you are going to buy more membership (Purchase Other Packages button). The payment page will show you the one/three/six/twelve month prices.
You should be charged in the currency that matches the country where you live.
I find I get a small extra 'currency conversion' charge.
