At the Turning Stone here in NY you get the chips at the tables (no cage). Don't expect them to look for your chips you want either, just spend your money and play the game.

I was told at the Service Desk to try ebay for a chip I was looking for (yeah right like that would happen for a current chip they still have in play).

Seneca Niagara in Niagara Falls I got chips at the tables. Same with Fallsview Casino in Canada (also at the tables). Akwesasne Mohawk Casino in Hogansburg NY I believe you can get them at the cage too.

I think if your nice and find the right person they'll sell you anything
