Cold Stream Farms from Michigan has Zumi, Sargent, and Siberian crabs still available in some form (mostly 1'-2') that you can get for under $1.25 ea if you order at least 25. Looks like they are out of Washington Hawthorn. I believe our local NWTF chapter used to order from them which is where I got most of mine from. They always did well except for the one year a "helper" had broke apart the bundles and laid them on the driveway. Dried out the roots from the start and many did not make it past 1st winter..... so don't do that!
