I mentioned grocery store cards. I'm pretty sure you know that while they show club prices on the shelf, many actively hide additional discounts by offering personalized discounts, right?

I don't every remember seeing places which are transparent about the discounts they offer staff and family off staff. At the very least, I've never seen signs listing those discounts.

Okay, it's not market segmentation. My comment was in response to what scott79 wrote: 'You have to put up a price and adhere to that price regardless of who wants to buy.'

That means that if I didn't list a bulk price and someone comes in and asks what the discount is for a bulk order, then, what, I need to refuse them?

Or can I can scribble the price on the tag right then, for the sale, and erase it immediately afterward?

I'm simply not able to figure out what the guidelines should be. I'm also not sure that "transparent" is that useful of a term, given how easy it is to put clauses in terms&services which people affirm without reading.

Or from HHGTTG: “But the plans were on display…” ... “It was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard.”
