Hello Shiftrick. ITCH.IO got back with me. During black Friday sales, due to the 1% discount, the website was ringing up all multipacks as single. I just got confirmation email from the website. This error was not caused by your company, but due to coding, I have been refunded, and am Buying 6 keys. 4 for family, 2 as Prizes when game is officially released. Ill send you a screenshot of the refunded sale.
