What currency should you sell your products in ?
PayPal is able to handle quite a wide range of currencies and you have to descide which currency you should sell your products in.
I guess the question really is “are you selling to the world or are you expecting payments from customers who are based in your locality ?” This will depend on the type of products you are selling. Digital products have the advantage that you have no shipping to worry about so you can choose whatever currency you want.
The only issue that I have discovered with selling in different currencies is to do with the set up of your associated PayPal account. If your ‘native’ PayPal currency is GPB and you want to sell in Euros, you have to tell PayPal to automatically accept ‘foreign’ currency transactions (the default is to ask). If you do not do this and you receive a purchase through your shopping cart you will receive an email saying something like “PayPal purchase verified and order is waiting to be processed” with body text of : “Unknown pending reason was received.”
Telling PayPal to accept all currencies and convert them to GPB resolves the issue.
