I have recently fell upon this site called Loot Crate where you can order a crate full of some geek gear for less than 20 bucks. They give you a word and the gear will be in relation to that word. The gear in the box is worth around 40 bucks and you have a chance to win a Mega Crate which is valued at around 750 dollars. We all know that buying geek gear can get expensive but this is a good way to help build your collection. I have ordered my first loot crate and I will provide you an update on it when I receive it. The word for the crate is Transform.
