Good. I might get to use my brain, I haven't done that in weeks.
Damn you Sherlock ! Next time the puzzles will be harder I assure you !
You've just linked to a slow cooker that is on sale at Robert Dyas for 11.99. That doesn't prove that they're always £5/£10 in Tesco.
I picked a very similar one from Tesco for about a fiver. They are normally that cheap tbh. https://www.robertdyas.co.uk/daewoo-stainless-steel-sda1364-3-5l-slow-cooker?source=aw&awc=1528_1590307141_189e0576758eb456a151e0e5f0a48a29&src=AW&affiliate=531573&utm_source=AW&utm_medium=affiliate ok may have been a tenner.
