I have bought all kinds of plants off of Amazon. Off the top of my head, I know I have ordered herbs, aquatic plants for my cherry shrimp, orchids, air plants and orchids/carnivorous plants in jars. I even bought my cherry shrimp on Amazon. I read the reviews closely, find the company's real website and learn as much as possible about them, then order. I haven't been disappointed. Sometimes I order from a favorite vendor from Amazon rather than their website as the shipping is cheaper through Amazon when I buy one or two plants. I have even found good vendors that I order from regularly now from their own website. So, if you see something you like and the price is decent, the reviews are good and the website looks legit... go for it...as long as it isn't 'Orchid Seeds'.
Just a note...this is in the US. I am not sure what vendors you will encounter. Good luck, though.
