I looked it up because I'm too young to remember ...
A "Stamp War" broke out in 1963/4. Fine Fare starting giving away the American S & H Pink Stamps. Green Shield Stamps were being given away by Tesco and Priceright and other stamp companies competed aggressively for outlets.
Lord Sainsbury opposed trading stamps. He formed the Distributive Trades Alliance comprising Boots, John Lewis, Marks and Spencer, W H Smith and other leading retailers. This challenge lead to an Act of Parliament to regulate the stamp companies. Fine Fare dropped stamps, but Green Shield Stamps remained popular for many years after this.
You would have to spend £32 to get just one book. In 1965 that would give you:
A set of six mugs in pastel colours Finlandia imported stainless steel tableware (8 pieces) A record rack A mouth organ A set of six lager glasses with gold rims A set of three pictures A cigarette box with a paisley pattern lid Stainless steel salad servers
It had a shoulder strap & a long lead so you could walk around with it on. I have a memory of my mother wearing it while washing dishes in the kitchen. Just imagine plunging your hands in water with that electrical thing on your head LOL
