Help me to spend £50 in M&S!

[DearTeddyRobinson]

I've been given a £50 voucher for M&S. I'm not too keen on their clothes apart from the knickers, and I'm certainly not spending my present on pants!
I know they have a pretty good beauty dept but I'm clueless what to buy. What are your must-haves for a knackered 42 year old mother of 2 small DCs? Is there a miracle potion to restore my lost youth?

I know birdsdestiny, they really need to totally rethink their business portfolio. Such a waste of all that shop space!

Do you live near a branch with a good beauty dept?
If it were me, I'd go in and enjoy browsing- they do have a great selection of beauty brands, as well as their own stuff. You could spend a happy hour making your mind up.
Failing that 25 boxes of toffee meringues.

I just spent a £40 voucher. I bought Pixi primer, mascara and a plain T-shirt.
