Simply go to your manage pledge button and select your reward level at the collectors edition – as we can only provide a limited number of them - and add the required amount to your pledge for the extra stuff you want. At the end of our Kickstarter we'll send round a survey so that we can take a list of all your extras and deliver them to the right place (remember to add £2 for shipping outside of the UK & USA - unless your order is above £300, at which point don't worry about it.)
