I can't really remember too much limited version of candies during my childhood, but I do know that I love anything that involves Reese Peanut Butter. I've found within the last few years they've been making a lot of new flavors that I don't see anymore. Such as Dark Chocolate Peanut Butter Cups and Reese Honey Peanut Butter Cups.
I was also a big fan of the some of the different flavor of the Coffee Crisp Bar, but my favorite was the Raspberry Coffee Crisp and Orange Coffee Crisp.
I don't how strawberry and peanut butter would go together with these M & M's, but if it involved peanut butter I would definitely give them a try.
One candy that I do remember from my childhood that I don't see anymore, even though I don't know if you guys down in the states have them anymore. Those are candy are called Bonkers:
Those where definitely awesome candy, I use to have them all the time when I was a kid.
Not to get off topic nutty, but if you want to talk about something that had a lot of different limited edition flavors in a very short period of time. Look no further than Pepsi products during the late 1980's and early 1990's. I specifically remember that Pepsi that a whole shit ton of flavors such as tropical punch Pepsi, strawberry Pepsi, and even raspberry Pepsi.
Obviously we got to remember this from the early 1990's.
Jam it back in, in the dark.
