I ordered from several vendors including Freshops, NB, Niko, Morebeer, & Thyme Garden in an attempt to get all the varieties I wanted.
Most disappointed with rhizomes from Morebeer and NB.
Best success was Freshops and Thyme Garden. If you are going to order the cheap low-end "twigs" from the big places, go ahead and get 2 of them per crown. I haven't had a double-failure that way and I got a more established crown more quickly.
