Bonjour Beverley ! That's an interesting question. The pronouns "Le/la même" refer to a previously mentioned thing = the same *one* whereas in this context (c'est pareil), "pareil"is actually acting as an adverb = samey/samely As an expression, "C'est pareil" is a more of a general statement, literally meaning "It's samey", which translates as "It's the same thing." I hope that's helpful! À bientôt !

In this case Beverley, you're using the adjective "pareil/le" meaning "identical/same", so when you say "Deux pareils, svp", you're literally saying "Two identical, please", which is indeed the colloquial way to ask this in French :)
