Savers (Waltham Cross) had loads of this in at least three varieties: Cosmopolitan (pictured), Pina Colada and Mai Tai.
They also had a selection of the Urban Decay Sparkly Sweet Body Powders You Can Lick (pack weights varying) at the same price (including Cherry Lemonade and Gimlet).
The cheapest price I have seen on the web is about £2.20 and I have never seen the products in shops for less than £2.50. I think the RRP is quite a bit more.
Nicely pacakaged and very good for stocking fillers ...... unless I am missing somehing here.
