I’ve collected mine over the last five years and they are a lot easier to maintain than you might think. I tend to buy them when they are reduced in price and always go for a double stem for a greater chance of a longer flowering season.
Mine are in a sunny window and are watered once fortnight where they are. I used to carry them into the kitchen and soak them in the sink (as some people advise) but it was a real hassle. Also, I don’t cut them right down when they have flowered unless a bit too leggy, because they flower again on the same stem. I use orchid food sparingly, not those individual droppers which would work out very expensive. I move the dormant ones to the back and have the best ones at the front, today there are several in bloom.
