Well, it just became a lot more expensive to buy books (or anything else Amazon sells) if you don't live in the UK.
"From 3 April, 2014, FREE Super Saver Delivery will no longer be available for deliveries to Belgium, Denmark, Finland, Gibraltar, Iceland, Luxembourg, Netherlands, Poland, Portugal or Sweden."
People were notified of the above in an email today... April 4th.
I get my subscriptions directly from Paizo (the smaller books), but hard covers I've always bought from Amazon.co.uk.
No longer it seems.
