SanDisk Extreme SDHC UHS-1 Card 32GB
Speed up to 60MB/s Class 10 '4K Ultra HD' and the barcode is 619659122850. Price was £13
There was also lots of other slower ones (Ultra) at similar or more.
Just watch out as this is also on shelves (still an excellent deal) but has slower speeds marked on it:
SanDisk Extreme SDHC UHS-1 Card 32GB Speed up to 45MB/s Class 10 'Full HD Video' and the barcode is 619659064556. Price was still £13 but obviously not quite so quick but still a better card than the basic/ultra for your money.
Hoping it isn't a wild goose chase as I have had a couple from different (local) Extra Stores and I would assume it is national as a lot of stock reduced. (Just to clarify there were none left in Southampton West Quay Home Store earlier as I had the last)
