edit *** LAST WEEKs DEAL IS BACK***
Today's Times newspaper (£1) has a coupon for a free £30 cut and finish at Saks, appointment needs to be taken before (**edit) March 24th. .
You'll have to be quick for this one, as I recall last time they "ran" this the free appointments filled up pretty quickley.
I couldnt find the deal on Saks web site but I would say it's confirmed as I've found it on the MSE web site.
