I went looking for some the other day. I asked the lady working there and she said they had moved it from the baking section back to the drinking chocolate aisle but that it was currently out of stock. She scanned it and it came up with a message (I can't remember the exact wording) but when I asked what that meant, she said it had had some sort of issue/problem with quality or packaging etc she said there are never details of the issue disclosed on the scanner just that that is what it means. So there was no expected time that it would be back in stock.
Just thought I would pass on the info. I had to then try and find some cocoa that had just cocoa on the ingredients list!!!
