I recently posted on how you could earn 500 free points with Priority Club.
You can in fact use this method to get another 1000 points: simply look at the answers on Loyalty Lobby and then fill in the “quiz” three times via i) the English UK link (if you haven’t already), ii) the English US link and iii) the Japanese link. All links are provided on the Loyalty Lobby page. The second and third entries will give you the extra 1000 points.
Obviously I’m not expecting you to be able to read Japanese – just work out which answer you need to click on from the English quiz answers.
