This is for online subscribers - had a response back from my email:
"We do ask that you allow at least 21 days for your first delivery to arrive, due to processing and packing time. Issues 1 – 3 are scheduled to be dispatched on the 8th September.
Each issue costs $19.99 inc GST (except for Part 1, which is $7.99 inc GST and Part 2, which is $12.99 inc GST). Dispatches are run approximately every 28 days. Charges processed 5 – 10 days after a dispatch."
Woohoo!
