Group Buy
Here you can participate in the early stage of product development, called Group Buy. A Group Buy is similar to a pre-order, with the difference that it happens before production has started. That's why the price is much better, but the terms are a bit longer.
Different manufacturers have their own timelines, which can range from 6 to 18 months. Because making limited-edition stuff is a complex process, the delivery dates are just estimates and might change. You’ll find the approximate shipping date for each item on its product page. Also, joining a group buy means you’ll need to pay upfront, and you won’t be able to cancel the order later.
Each project has its own order start and end dates. Once the order period is over, you won’t be able to place an order, and all orders will go into production.
