This is my first deal so please be nice. :)
Was in my local Morrisons sulking about missing out on the cheap champagne when I thought I'd check the wine isle and saw that my fave champers was reduced from £31.95 to £24.91 and it also has a nice ice jacket that apparently keeps it chilled for 2 hours.
I think it's nationwide but I'm not 100%.
Edit: some info taken from another website:
The perfect alternative to an ice bucket, the Clicquot Ice Jacket comes with a 75cl bottle and fits like a diving suit, keeping the Champagne cold for up to 2 hours.
In their distinctive Clicquot yellow colour, this uniquely constructed neoprene jacket is as soft and as light as a feather with top-stitched seams, leather trimmings and a convenient zipper closure.
Slip the pre-chilled bottle into the chic Clicquot Ice Jacket and enjoy the freedom and elegance of taking your bubbly wherever you go: the beach, a picnic, for a moonlight stroll.
