Thank you so much for wanting to join OwlCrate! As we only build a limited number of boxes each month, we can sell out.
When the site is in sold-out mode, the best thing to do is to join the Wait List. Once spots open up, we will start contacting those on the Wait List, in small batches and in the order in which they joined.
If you are looking to give OwlCrate a try or are looking for a gift, you can check out the Past Boxes section of our online SHOP.
