>>10704747I Just go to the mall...
Oxford Valley Mall in Pennsylvania has a 2nd-hand Lego store. They sell individual minifigs and pieces of all kinds. no shipping needed! (but to be fair there's a $3 toll road to get there, I'm the shipping cost! lol)
There used to be a store in Nyack, NY but I haven't been there in many years so IDK
And Lego itself has a pick-a-piece thing right on the shop website, you can pick individual things there but I'm not sure how "old" they'd get (you might be surprised)
