I don't know of a place in TN that sells agate slices. You might try attending a gem and mineral show. They always have them, some polished, some not. Google for "gem show"+your town, maybe you'll find one. Most big towns in TN have about 2 a year. You've got mail!

Here's a site for you.

Thanks for the info. I am not looking to travel far to get any, as I am not looking to aquire that many. Just need about maybe 30 or 40. Didn't realize the had went up in price either. Bought some to make necklaces several years ago they were pretty cheap then.
