Saw this deal on HUKD.
30% off the 12 month PS Plus price as part of the Days of Play promotion which will also be running in Australia.
A screenshot taken by Chanchi32 which has since been removed shows that the deal will be available for both new and existing users.
This deal is likely to proceed as Target will be running a similar offer on June 7.
