Hi Victoria,
Why not just get the other orchid and grow both plants? If the first one makes a recovery, then you can gift or trade the second one. If not, then you still have the Milt that you really wanted to grow. I think it is personally a good idea to buy from different vendors to find who grows her/his plants the best as well as how they ship (says a lot about the care they put into the orchids). Good luck!!
Cheers,
