We've seen limited edition chocolate flavours come and go, but some people just won't forget about their favourite treats and will do everything they can to bring them back to supermarket shelves!
One man in the UK has started a petition to bring back Cadbury's Snow Flake, a flake bar that has light white chocolate in the middle of a milk chocolate casing.
John Malogony started the petition on change.org, saying that Cadbury "broke hearts" when they discontinued the treat in 2008.
"In 2008 Cadbury broke hearts by discontinuing the Snow Flake (or Flake Snow). The bizarre decision still baffles people to this day and it needs to be rectified.
"Say it with me now: BRING. IT. BACK! BRING. IT. BACK!"
Over 4,582 people have signed the petition at the time of writing and it looks like there are a lot of very passionate chocolate lovers!
One signee wrote: "I’m signing because the Slowflake should never (of) disappeared in the first place. I remember when I realised they weren’t being sold anymore. I couldn’t leave my house, I was scared, disorientated and paranoid.
"The Snowflake may not seem like a big deal to all you big people in your big houses and big offices but down here in the only average/slightly above average sized houses/offices areas of the England it does ok, and I’m not just going to stand here and not do anything about it ok!?"
If you think the Snow Flake should be brought back as well, you can sign the petition here.
