According to 'My Subscriptions', the Iron Gods #2: Lords of Rust book was shipped to me on the 19th. I haven't received it and I also never received the confirmation email telling me that an item has shipped (which is what led me to check My Subscriptions in the first place). While that's still within the 4-8 day window of delivery, I've never had a subscription take more than 3 days to arrive after receiving the confirmation email. However, I never got that email. This is the first time a product has ever been late and the first time I haven't received a confirmation email so I'm worried that something's fallen through the crack somewhere. I don't see an order # listed under My Subscriptions.
I've resent the the confirmation email. It looks like the tracking information started updating yesterday and it should be on its way to you.
If you have any further questions or concerns, please let us know. Thanks!
