Are we about to lose another good thing? 😭😭😭

I’ve been looking for This Isn’t Chicken Thighs in Tesco and Sains for weeks. I used to be able to find them with ease but not anymore. I had a look online and now only Waitrose stock them apparently. These are my fave things ever! Are they about to disappear from shelves? I love them so much. I’m in SE London. Has anyone seen these in store? 😭😫
