"But were they Black..."
I bought a 500g punnet of black grapes from Waitrose this afternoon in the small window of opportunity after they do a final*** price slash on "last day" fruit and veg. £2.50 down to 89p.
***If you go 15 minutes before closing time - they often do "everything 10p" that's still left in the "last day" trolley. Works really well if in the shelf restocking they have suddenly discovered nice things with expiring dates. Recently the lady on the cheese counter came looking for me as I was browsing the trolley. She offered me an overlooked 1.6kg unopened pack of Blue Stilton for £2.90 a kg. Several neighbours' households shared in that windfall.
