Timely response and delivery!
I initially used another website and waited 24 hours and contacted customer support just for them to tell me it was out of stock. They didn't even want to refund me. Offered me game gold. I tried D2R for the first time and they contacted me and let me know it could take 6-12 hours because of low stock and that if it wasn't delivered within that time they would automatically refund me. They delivered it within 2 hours!
