plugin for multi currency priced products linked to paypal

I need a very simple link to paypal for a website selling a maximum of 5 products but I need customers to choose to purchase in at least 3 currencies for every product € £ and $. I have already installed WP Simple Paypal Shopping cart but I cannot find another simple plugin to do what I need. I would like a shopping cart preferably, but I do not need anything more complex and I am not a coder. Can anyone suggest anything? Thank you
