Hey, I don't know whether it has been brought up, but it is free to subscribe during alpha!! I just found out, and wanted to share with you all!! I got it by going into the wardrobe, and clicking on a subscriber-only item. It will pop up with the little thing saying you need to pay five dollars, then below it, you will see 'It's free to subscribe during alpha, join up now!!'
Thought you might want to know.
Happy Glitching, jjbob
