The merchants do deals not for the customers, but for themselves: to maximize profit, increase market share, and maybe achieve some other goals. If you guys are communists, and think corps are evil, and the poor are exploited, that's fine, but how can you hope to successfully operate in any industry without comprehending the basic motivation of the principal actors?
> To paraphrase what the fine folks in the US like to say, the world doesn't owe you a deal.
I’m from the US. 40% of us believe the earth was created a few thousand years ago. Be immediately skeptical about anything we commonly say. (http://www.livescience.com/46123-many-americans-creationists...)
(And it even contradicts the whole point of the "US". We’re born into all sorts of bizarre deals, like the so-called social contract I never consented to.)
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.
ie. if what you're saying were true, why are there still businesses that only give deals to people who hunt for them?
