Where can I buy top-up vouchers in Spain

[JulianS]

I'm currently traveling through Spain and am wondering if anyone has any knowledge of places where one can purchase O2 UK top-up vouchers. I am based in N.America and am unable to top up by credit card as I don't have a UK address. Online retailers such as mobiletopup.co.uk charge a mark-up, which I would prefer to avoid. I would prefer to buy at a local phone shop here (Spain) offering O2 UK vouchers (if available).

You cant I am afraid, as shops in Spain only sell top ups for Spanish Networks. 

Your only option is mobiletopup.co.uk or try paypal.

Thought to ask on the chance there might be a phone shop that catered to the tourist market. Thanks for confirming. If I do happen to find such a shop, will post here.
