I can buy Cake Craft & Decoration locally on the newsstand. The store saves me a copy every month and (when they remember) will phone me to say it's in. (The March issue arrived on March 9.) It is cheaper for me to do that, than to buy a money order in sterling, mail it to the UK, and risk the postman mangling the magazines.
THIS MAGAZINE TOTALLY ROCKS.
Especially if you are into fondant. The pictures are stunning and at first glance look pretty scary but all the cakes have detailed step by step instructions with photos. Ads are kept to a minimum, mostly in the back. The contests are virtually all UK only.

Talk to your favorite magazine retailer about ordering it for you. The editors usually have a booth at ICES and sell not only subscriptions, but 4-6 months' worth of recent issues.
