You have to know what the seedlings are like too. I've ordered from Missouri MDC, PA's PGC, local NY county Soil & Water, NYS DEC, and NH State nursery. For me, PA's PGC seedlings are the cheapest but also quite small and they are struggling to stay funded and open. I find the MDC stock to be excellent and priced pretty well but takes a lot longer to dig each hole to plant. But I mostly order based on who has what I want and will ship to me rather than pricing. NH has red spruce that I want to plant sometime and some occasionally some unique natives. MDC has a nice list including paw paw, persimmon, and the shellbark hickory that I want to plant next spring.
