We just have a different view.

In a highly-competitive marketplace, the stores that treat people right will win volume. Those who win volume take the market. So don't rip customers off (or be extremely quick to correct it when you're called out) and you'll gain customer loyalty and all the subsequent transactions.

The world doesn't owe you a deal, but then again, the customer doesn't owe you their next purchase. Life is long. As a store, your job is to keep earning customer trust so they come back.
