NOTE: Limit one (1) entry per person.
So do the rules mean one entry per pack per person so players can enter for all of them, or just one entry between the sets so players had to choose? We asked in response to the tweets, and @play_pso2 have just replied to confirm it's the former:
Hey there! One entry per Prize Pack, so you can try your chance for each! Have a great one!
So feel free to enter for all of them!
