One Saturday lunchtime my dad came home from work with a £20 bonus (this was 1983). He said he thought he'd buy one of those computer things at Rumbelows (this was 1983) and a little later we returned home with a ZX Spectrum and 3 games - Space Raiders, Snooker, and Escape...
My dad had to go back out maybe an hour later to buy a new tape/cassette player because ours didn't have the right plugs.
