Bizarre phrasing, but you have to fit the gist of your OP into the subject line.
Whenever a consumer feels like they’re getting a deal, especially a great deal, they’ll invariably spend more money and buy more. The same person that may reluctantly spend $10 on two items at the drug store will spend $20 or $30 at an “Everything’s a dollar” store because of the perceived deal at hand, even if they hadn’t intended to spent that much money in the first place. I think of it as “the Ikea Effect” - Ikea customers are constantly loading up on tons of the cheap things that the store sells - $2 packs of batteries, $3 bundles of hangers, $2 umbrellas, and so on, “because they’re such great deals.” I saw this in action recently - a friend who was shopping with me was too broke to buy groceries, but ended up buying almost $30 worth of this cheap stuff, because “…but it’s an umbrella for $2!”
I just think that this is a very fundamental aspect of human psychology - when someone perceives that they’re getting a deal, they’ll spend *significantly * more money than if they think things are priced “normally.”
I’m stingy when it comes to books - I think that especially since the industry-wide shift to trade paperbacks over mass-market paperbacks, books are way overpriced (aka, the “I should be able to buy Crime and Punishment for less than $18.95” effect). Because of this, I tend to not buy books from places like Borders or Barnes and Noble - I’ll buy them online or used when possible, and even then, grudgingly. But I recently found a local bookstore that sells remainders - books that didn’t sell well and were returned to the publisher to be blown out at discount rates. I embodied this psychological effect in this shopping trip - I spent almost $100 on remaindered books (that were really only 30% cheaper or so than if I had just gone to Borders) when I wouldn’t be able to bring myself to spend even $20 on a book at a chain store. I felt that “because I was getting such a great deal,” I had to really make the most of it and buy buy buy.
So why don’t more retailers exploit this fundamental pyschological effect in their pricing? Imagine if tomorrow, Borders suddenly announced “every item in our stores is 30% off, permanently.” Besides immediately putting Barnes and Noble and Books-a-Million out of business, Borders would CASH THE HELL IN as people flocked to buy discounted books. People that may spend only $15 in a borders trip would drop $50, because they’d be getting more books for it. And they’d do it more often. The amountof money lost by discounting the product would be more than recouped by the increased volume of sales due to the psychological effect.
But why not take it further - I always wonder why certain gas stations don’t just make a habit of always selling gas for $.25 less than the average rate - people would FLOCK to them, and I guarantee they’d do twice the business that they currently do.
I just realized that this might be better suited to IMHO, but I think that there may be a factual answer to it, so it goes here for now.
