@TheForgotten20 within 1 day of the update I had over a dozen people tell me that they would've started selling anywhere between 5 diamonds/box to 9 diamonds/box. I set up the most ambitious shop in the history of the server in the sense that my partners and I decided the price to preorder an item that wasn't even in the game. The type of planning and thought that went into my shop is unparalleled, and even so I decided not to rip you guys off. I've made far fewer diamonds making my grinder than I could've gotten by mining for the same number of hours
tl;dr my price has been more than fair. I could argue that I've actually lost value by providing this service to the community rather than mining
