I recently put together a
group purchase for Floralia Orchid Nursery in Brazil. Around 8 of my plant friends participated and we ordered enough to receive a 30% discount. The plants were all in good shape and accurately matched their size description on Floralia's website.
A while back I organized a
group purchase from Oak Hill Orchid Nursery. Unlike Floralia, with Oak Hill you there is no minimum total you need to purchase in order to receive a discount...you just need to purchase five of the same plant.
So my recommendation is to cultivate a good group of enthusiastic plant friends in your area and/or join your local orchid society if you have not already done so. Another alternative is to try and sell any extra orchids at cost on
Craigslist. Doing so is also a great way to meet other local orchid enthusiasts.
