If you're still interested in other online vendors, I recommend Naylor Creek, Northern Grown Perennials, Made in the Shade, Land of the Giants, and if you're on Facebook there's a group called Hosta Buyers Guide that have lots of vendors offering plants all through the season. You'll have to search for the group and then ask to join. I don't think it's a public group.
Have fun going broke!!! It's easy to do!
