As I understand it, the monthly magazine is just pictures (lol, no change) and will be widely available in magazine outlets.
The weekly magazine will only be available from
GW so you subscribe or you [sneaky plan]visit your local
GW weekly[/sneaky plan] in order to get a copy and attracted by the new shinies of spreading new releases weekly you make an impulse purchase and buy some models to go with the great rules/tactics/bat reps/columns that the weekly magazine will contain.
And now your monthly magazine cost is £10.40 (on average) + the cost of the monthly mag (if you have a hankering for pictures).
Cunning no?
