Well, I negotiated Tesco successfully.
They're now sanitizing the trolleys and have perspex screens and the full works. Stock levels are almost back to normal, but tinned tomatoes, flour and chocolate biscuits are still conspicuous by their absence. Oddly, there's plenty of pasta, baked beans and bog roll on the shelves...
Got everything I wanted except for tinned tomatoes, and managed to get ham, polish sausage, cooked chicken, avocadoes, fruited teacakes and hot cross buns on yellow sticker.
Also bought some easter gifts - beers for my neighbour, and some bars of thorntons 70% dark for assorted friends, some of whom are self isolating. Those will be hitting the post on Friday.
