Not that I judge what somebody says by the way they spell... that would be unfair... but I just thought I would create this thread for people who just want to know the difference :)
There is usually a direction or describing the state of something. "Put the chocolate over there". "There is usually a good reason to hide your chocolate if you have kids in the house".
Their indicates ownership. "Their range of chocolate is the best". or "The chocolate is theirs, not ours".
They're is short for 'they are'. "They're going to be sorry if they eat my chocolate again!"
I'm not the world's best speller but this little set of words is handy to know :)
