I'm going to pipe in, I may get my head bitten of for this but hey ho!
When it comes to Mass Production and the Big Stores, it's all about Turnover and Display.
Once that Noid Orchid (or indeed plant in general) starts to loose it's blooms as far as the store is concerned it can not be sold for it's full price, because they consider most of the GP (General Public) to be ignorant or the store themselves are ignorant.
So the plant, still reasonably healthy may be reduced, and that is why you can get a healthy Noid for such low prices.
The Grower may give the company a credit note, but will not necessarily take back the plants. Why? You ask. Think of Space! How much the grower has, they may already be producing new batches. It may also be economically non viable to return the plants to the original grower. So the plants, most of the time, get Chucked if they are not sold!
So yes, you can get very healthy Noids for ridiculously low prices. And if that helps someone get Interested in Orchids then eventually they will learn more and gain wisdom. As the newbie will gain experience and learn from their mistakes, and even find a forum like this one to help them along the way.
If you wanted to experiment on a plant type, would you spend a lump sum on One Plant, or the same amount on several?
If a cheap Noid, which even at full price can be cheaper than a bunch of cut flowers, can inspire someone to have more confidence and gain a true interest in Orchids where is the long term harm?
If they are truly interested then eventually they will move onto True Hybrids and even Species.
If you are just starting out, it can all be very daunting.
This goes for any Hobby, Interest and or Passion. And if you don't know the ins and outs (or find a forum like this one) you are likely to over spend and or get stung.
As for expense, Orchids are not the most expensive interest I can think of by a long run, but only if you do some research and find those reputable growers. And if you only want a few plants, well the cost gets even lower.
So for a true beginner, who's just starting out a cheap noid can be an invaluable and inexpensive way to start. If they decide they're not as interested as they thought they would be then they haven't lost too much. If they decide that they are truly interested then more often than not you will find they will become far more discerning in their future purchases.
If you want to get rid of the mass production side of Orchid Growing then the only true solution (that comes to my mind) is to spread the knowledge to the GP.
It's all about personal experience and spreading the knowledge at the end of the day.
I would not advise buying an unhealthy plant, no matter how cheap it is, unless you are made of money and know exactly how to bring it back from the brink.
But a Cheap Healthy Noid? Why not? If it sparks a keen and true interest in the long term!
... All just my

at the end of the day! Please don't bite my head of for this general opinion (it's not very tasty anyway)
