What a great idea. I wonder how much it is?

Propane cylinder exchange at The Real Canadian Superstore, Vancouver, BC

Propane cylinder exchange at The Real Canadian Superstore, Vancouver, BC (Detail)

Anyone with a barbecue has likely had to refill their propane cylinder. But what could be easier, and safer for everyone involved, than just exchanging your old empty cylinder for a new full one? And, you may ask, how much do I save by refilling my old cylinder?

At this Real Canadian Superstore location you have no way of knowing.

Marketers talk about the central principles of marketing; the 4Ps. Product, place, promotion, and price. Of these four, most people would say that price is the most important. In most cases price is what the customer notices first, even it is not the trigger than makes them buy or not buy.

So while this display has a place for the prices, both with and without cylinder exchange, there are no prices in evidence.

This is yet another of the million little details that retailers need to get right. Get them wrong and not only do you miss sales opportunities, but you may drive your customers elsewhere. And the worst part of that is they may not come back.
