Just saw this in John Lewis, Bristol. Couldn't quite believe the price so I took a photo! Wasn't maked as a clearance item so should be plenty of stock available.
Might be useful for anyone not able to find one at Asda.
This price is not available online.
If you ring Bristol (0117 9591100) they will send you one direct from the distribution centre for free (wherever you live). Thanks PeteW!
Atlernatively you can ask your local John Lewis to pricematch the Bristol branch (thanks bossyboots). It seems they are usually offering free delivery when you do this too!
