From the announcement:
Times have changed a great deal since the SOTCW first began. For some years, people have been asking for the option to get The Journal delivered as a PDF instead of paper. For various reasons, not least rapidly-increasing postal charges, we have decided that we have to start offering PDF copies of The Journal as well as paper copies.
Subscription 14 (Journals 83-88) is therefore available as a PDF-only option, at the reduced price of £12, from Wargame Vault.
