Where are the other downloads I purchased

Those are in the customer dashboard area where you originally downloaded the Volume 1. 

As was mentioned on the Thank You Page, there is around a 20 minute delay for those to post after you see the first download. That's just a twist in how the ecommerce company has digital deliveries. I'm not sure why it 's that way, but that's just how it is (even though I wish it were instant).

So just go back into your customer dashboard and you'll see the rest of your order there.
