I've never thought of getting bulbs from there. I rarely go, the DH does most of the shopping. I'll have to keep them in mind this fall when it's time for bulbs shopping again. As a matter if fact, I need to see what they have in for spring.
Years ago I bought peonies and hostas from SAMs. It took a few years for the peonies to bloom, but they're wonderful now, and the hostas are still going strong.
