So a few months ago I ordered 1,500 rounds from Bass Pro in Portage and about 3 weeks ago they called me that my order came in. I would say order online and just wait. Blythes in Griffith seems to have some too depending on what you are looking for
I got a thousand rds of 9mm Speer hardball from Natchez about 3 weeks ago. They had it in stock and delivered in 2 days. Don't know if they still have it. I paid a little less than $285 including tax and delivery.
