Woolies (and Big W) - loved those red slot machines you put 10p in and got a mini dairy milk. and their huge toblerone bars- 3 for a fiver near Christmas
Kookai (ok that is going back a bit!)
Wimpy burger bars (even further back)
Bookends (new cheap books and also a whole basement of second hand books. I loved it there. There was a branch in Bristol and one in Gloucester)
An online shop called The Winking Cavy Store which was full of gifts, jewellery etc all guinea pig related!
Discontinued things (this is going to be looong):
Terry's Pyramints
Terry's original style choc oranges (the new ones just aren't the same)
McDonald's McRib
Ben and Jerry's Chubby Hubby (with peanut butter pretzels in vanilla and chocolate swirls)
Terry's Nepolitans
Terry's melting moments bars (early to mid 90s- hexagonal chocolate squares with hazelnut and caramel and they also did one with mountain shaped segments and white chocolate "snow" on the peaks)
Cadbury's Snowflake
Fry's 5 Centres (this is cheating a bit as by the time I was born they discontinued it, but when I read about retro choclate and this bar always comes up, I feel sad that it was discontinued as sounds so good. Ditto Cabana bars and Banjo bars)
Wall's ce cream Tacos
Gino Ginelli ice cream especially Choc Hazelnut and Tutti Frutti
King Cones (not Burger King but those huge cornets you got from ice cream vans)
Shaders and Toners- wash in wash out hair colours
