Can't find any reference to this on their website for the T&Cs, but it worked on my order.
Description when using code is 10% OFF IN STOCK ITEMS.
Some comments on previous PopCultcha posts would lead me to believe that you need to have an account to use the coupon code.
There shipping is free once you are at $100+, but $9.99 otherwise. However, when I added an item that was $109 and used the coupon code to bring it down under $100, I still received free shipping.
Thank you, I just combined the code with their current warehouse clearance sale and got myself a bargain on this already discounted Hot Toy!
