Brand New To This, Any Advice?

I just ordered my very first setup and now its time to get some records! For some reason, I already own the Super Mario Bros movie vinyl lol, but I certainly need more! Where are the best sites/stores to get these (I am in Manhattan in case anyone has store recs)? Also, are there a lot of “fakes” out there or are there certain things to look out for? Any advice you may have for a beginner would be much appreciated!!
