No, you ring up their customer service number and ask them to post it to you (which they will do, via DVD). It typically takes around a week to arrive so do it without delay. They usually agree to put the discount on hold for a few days to allow time for it to reach you, but make sure they confirm tihs on the phone (occasionally we hear of a call centre worker who isn't familiar with this policy and denies they do this, so do stand your ground if so).
Once you have it, upload to youtube or similar and post a link here. The photos in the PCN don't look promising, but it's the video which counts.
