Home Depot, Lowes, Wally World (Wal-Mart) .
I got my last bag of RO at Wally World .
Try cooking with it the first time without any chip,chunks etc.
It is burned Oak wood and is very good for smokeing with out use of chip,chunks etc.
After you know what it does all by itself then you can consider if you need to try different type chips or chunks for different flavors .
It is very good just by itself .
Trust me and try it .
I think you will like it .
Try a Google search for Wal-Mart and Royal Oaks and see what comes up maybe .
