The website shows prices in Euro. How much is this in my local currency?

The exchange rate varies day by day. If you wish to know the current rate, just ask Google with a search string like:

"50 euros in USD" without the quotation marks.

Or you can use the website http://www.xe.com if you are a high finance passionate and need more detailed informations about the exchange rates.

Anyway, the moment you send the payment with PayPal in a foreign currency, PayPal informs you about the actual amount in your local currency just before you confirm or cancel the payment.
