Consider BrickLink as a kind of an eBay or Craigslist for the popular toy brand, including for replacement parts that have already gone missing from holiday gifts.
BrickLink also has a full selection of LEGO books, including Harry Potter, Pirates, Superheros Batman and Justice League, plus sticker books and magazines.
The LEGO site also offers hard-to-find collector sets, and there’s a helpful “wanted” section for you to list what you are missing.
Or, you could go to one of the LEGO stores in NYC, in Rockefeller Center and in Flatiron, and pay more, unless you take advantage of a LEGO giveaway.

There’s also a large LEGO outpost in the FAO Schwarz toy store, also in Rockefeller Center.
