Absolutely loving this thread! Bought back so many great memories! Especially finding a toy in your cereal, completely forgot about that and gave me so much happiness like I was 8 years old again
To add a few:
Tamagotchis
Furbies
McDonald's having the Ronald McDonald foundation donation box where a coin would whirl around for the whole time it took for them to cook your Β£1.99 happy meal
Petrol being less than Β£1 a litre
Teletext so grandad could check his lottery numbers or the football scores
Yellow pages
Goosebumps
Rosie and Jim
Cassettes
CD singles
The Walkman - that would always skip a bit of the song if you walked too fast and heaven forbid trying to run with it
The foil Christmas chain decorations that your mum would use a drawing pin to stick to the ceiling
Playing "kerbie" in the streets and seeing other kids playing out in general
Being able to leave your push bike out in the driveway whilst you went inside to have your lunch and it wouldn't have been stolen!
Sunny D
School sponge cake (the one with all the multi coloured sprinkles on the top)
Supermarkets leaving their old cardboard boxes out for customer's to pack their shopping in to
The weird goo alien toys that would "make babies" if you put them back to back in the fridge
The millennial coin collections they done in Sainsburys (I think)
The battery hair braid thing that would tangle your hair into the biggest knot and rip most of it out
"Scoobys" the plastic string things you could plait together and make key rings out of
Push pops
Blow pens
Penny sweets
McDonalds birthday parties
And a ps2 that could play new games and all the original ps1 games as they were transferable without having to buy a whole new console (like you do now!) And the memory sticks that would sometimes not save your game or would be "full" and you'd have to play roulette deleting another save game which you hope wasn't the one with your best score
