........even some foods have disappeared or renamed.

Roast mutton was one've our favourites for childhood Sunday dinners, only 'lamb' available now.

Also, being able to buy loose stuff, that is unpackaged.

At the greengrocers, you took your own bags & got loose spuds, carrots, cabbage etc by whatever weight or quantity you chose.

You could get 2 ounces, a quarter etc of sweets & at the ironmongers loose nails or screws either singly or by the 1/2 pound, 1/4 lb etc.
