Is it possible to buy this plant online?
It would be easier to buy it at an online shop specializing in orchids, as it's more complete.
You can buy it at Orchids-R-Us, Guna Orchids, Orchid-Tree, and AmThai Orchids. Or, even better, you can buy it online at Amazon! Ebat is also available.
The great thing is that you can actually buy these plants from local orchid societies, which will have a fantastic selection to choose from!
As I understand it, Amazon is a popular online store selling plants
There are so many in online stores! I'm happy to tell you where I bought this Oncidium orchid plant. You can check OrchidWeb, Etsy, or maybe Amazon and eBay!
