Buying Subscriptions Through Kindle Newsstand App

Lee Griffiths

I've a lovely new Kindle Fire and looking to go digital with my 220 subscription. I've looked in a recent magazine and online and I must be a little dumb. 

I can see how to buy digital from buysubscriptions.com, but don't know how online to Kindle's Newsstand. I can't see the subscription available in Newsstand either. I'm too nervous to buy a load of subscriptions if it's not possible. But then the physical magazine says it's possible. I'm confused, or maybe I've had too much turkey and mince pies today!

Any help or stsp-by-step or confidence it is simple once I've paid the subscription through buysubscriptions.com! Cheers Lee
