Thank you for playing! Happy to hear that you like it!
If you already paid, you only have to add the difference ($3 in your case) :)
Oh, that's awesome, thank you so much! And yeah, I love it. Started replaying it again last night, and I'm already noticing things I overlooked last time. $3, coming your way!
edit: I think I may have screwed it up on my end. I have the game two times now but no pack XD As long as you got the full $8 though, I guess that's the most important thing.
