I would buy from one of the places on the top thirty list at garden watchdog.

I would choose the source on that list that is geographically closest to you—shorter shipping means better condition. Type of bulb is going to matter as well. You need to choose a bulb that is suited for your gardening zone, soil type, etc. Also, some bulbs are just better at reproducing themselves in the garden than others, Tulips generally don’t last long as daffodils, etc.
