I didn't know you needed a licence for such a thing, but that does explain the one solitary store in Spitalfields.
As I may have mentioned before, AmazonFresh had been reducing their own-label fresh stuff over the last year in favour of a ragtag mix of Morrisons and Booths, though the ambient range was still going strong, presumably because they can still sell it online. Indeed I just bought a case of tinned tomatoes to make up an order to be eligible for super-saver delivery, and they're better quality than the ones we'd previously been getting from Tesco.
