I read a lot of magazines and have a handful of favorites which I repurchase on a monthly basis however Glamour is not one of them. The last time I bought it they were giving away a Nails Inc polish.
This is a great deal - a mascara which retails for £9.50 for £2! There are three covers to choose from. I opted for Fearne Cotton (not sure if this effects the mascara?).
Grab yours while you can :)
