Was in Tesco this evening and picked up a pink snuggie blanket reduced from £14.99 to £7.
About ten left on the shelf.
'A one size fits all super soft pink fleece that keeps you warm and your hands free. Made from polyester, the Snuggie is machine washable.'
In store only still full price on their website (although only blue and red). Might be just my store so would be interested to hear it available elsewhere.
