From what I can tell, this picture is all what will come with the magazine over the course of the whole series.
People in the comments are saying it's 8 pounds per edition, and 80 editions in total.
[quoteWebsite for this says:
Standard Subscription Pay £7.99 (€9.99) per issue and receive 4 issues a month. Includes 5 free gifts and one free issue
Premium Subscription Pay £9.49 (€12.49) per issue and receive 4 issues a month. Includes 5 free gifts and one free issue, plus your 4 Premium Wargear sets.
Edit: site also says 80 issues, £7.99 starts from issue 4 onwards so total cost over £600
