powerup, the whole heap of the documents are available online, which can really help you save some cash.
CAO and CAR are available from the CASA website
AIP and ERSA are available from the Airservices website.
You can print off the CAR and CAO, and with a little planning you need only print off the stuff you really need. Leave off the CASR entirely; you cant yet take it into the exam.
Buy an AIP - printing that is painful. If you borrow an AIP, make sure it is current.
