Einmal hin, alles drin.
This is the motto of Real.
I know it means that you go to Real shopping for one time, you can get all you need. Are "hin" and "drin" single words or prefix?

I know in some mottos, people usually use brief expression and omit some verbs. But that made me not understand the grammatical structure of the sentence, could you give an example of the full sentence without omission ?
