Not sure about the bundles of wood but, they do sell the logs and packets that will produce colored flames in your fire. Brilliant greens and blues and the effect does last for awhile. Any Speedway sells the bundles for about six bucks.
I think Menards does sell small bundles of wood for outdoor fires. Even my local cub foods, hardware store and gas station does too from time to time. Check outside front entryway typically.
