Looks like a decent deal. You get 30% off any crate you purchase (Most likely single purchases turn into monthly plans, but they also have one off loot crate purchases).
There are multiple types of loot crate to chose from. I have been ordering their Gaming crate since last year October and was on a monthly plan paying USD$34.95. I subbed to a 1 year plan now with the coupon code and it comes to USD$22.36 per month now.
I get a tshirt a month and bunch of other cool stuff I can decorate my gaming room with, plus the odd gloves, beanies, socks, car sunshade etc, so pretty happy with my crate so far.
If you subscribe to any 3+ month plan you also get a mystery crate worth $40 for free. Subbing for 1 year also got me a T-shirt free from the looks of it on top of the discount and the mystery crate. :)
Happy crating!
Oh God… It's that word again… Loot crates.
