We bought this orchid from the supermarket last year, it was reduced as the flowers were just starting to drop. The main reason for this is the supermarket doesn't look after them properly. Placed on our kitchien windowsill and looked after it has thrived and now looks like it's getting ready to uproot and move itself to a better plantpot.
The best thing is over the last couple of weeks it's starting to get ready to come back into flower. Not sure how long it will take as orchids tend to do things in their own time but the flowers do last for weeks once they bloom.
