My guess is not lately.
When you first got a fancy job, you had a tie shortage, and thus attention was paid to ties. You bought "enough for now." Then you solved the tie problem and moved on.
When you first bought an iPhone, you had an app shortage, so attention was paid to apps. You bought "enough for now." Then you moved on.
Music might be an exception (buying a new stereo doesn't often lead to a new music binge). But in general, some external event occurs that creates a fissure, an opportunity, a problem. We search, we buy, we're done.
