If you can't find anything sold locally, we use Fisher Scientific (https://www.fishersci.com/) at work. They have a warehouse in Massachusetts, and when items are in stock at that warehouse, they're usually delivered to me next day (so long as the order is placed by 2 pm). They can usually tell me over the phone whether my item is in stock and where, too. Give them a try at 800-766-7000.

I know it's not your first choice, but hopefully this helps.
