In theory it could, although replacements that happen that quickly depend on stock-holding.
It means that sellers understand the importance to the business of providing good after-sales service, and sadly many suppliers just don't get it.
I'm not saying it's easy - there are all kinds of pressures on suppliers - but happy customers will often do what you've done, and the message spreads.Over time a reputation is built up, and the rest follows. Then comes the difficult job of maintaining standards as sales volumes increase, but that's another story.
It all starts with senior management, and in my experience that's often where it grinds to a halt or to put it more precisely, doesn't get off the ground.
