It's about time for me to renew my sub to B&W (UK) and I got a letter from Lightning Publications about it. But if you subscribe online it goes through the GMC Group. So I just wanted to make sure I do it right! Is it correct to renew through Lightning?
Looking at the prices, you are much better off financially going through Lightning. I have no idea as to their quality/stability/etc - it may be worth asking what happens to your subscription if Lightning were to cease trading for whatever reason.
The price differance may well be partially down to the postal costs. UK postage is not cheap and it is probably far more economic to ship a number of magazines to to the american continent in one parcel then have them distrubted there.
I've just spoken to our subscriptions department, and have been told that if you are an existing Lightning Publications customer, you are better off renewing through them, so feel free to renew online through the link that Robert very kindly provided.
