Sainsburys grapes confuse me.
500g of white grapes are £2. 500g or red grapes are £2.20. So you’d expect 500g of half-red, half-white grapes to be… £2.10, right? But no, that’s £2 too.
So buying 500g of white grapes and 500g of red grapes is cheaper if you buy the mixed packs and then separate them. Why!?
