“…the average person treats a price ending in .99 as if it were 15 to 20 cents lower.”
The tendency is called left-digit bias, when the leftmost digit of a number disproportionately influences decision-making. In this case, even though the real difference is only a penny, research shows that, to the average person, $4.99 seems 15 to 20 cents cheaper than $5.00 – which results in selling 3 to 5 percent more units than at a price of $5.00"
Not trying to debate you at all. You are free to believe what you want to believe.
The title of my post is that people see those 99 prices and then continue to sell their items using whole numbers without questioning it. So, in your responses you validated my post title.
Right, and my point is that we don’t question it because it would be absurd to sell one-off items on-digit-removed from the actual selling price. I wouldn’t buy anything from someone selling shit on craigslist for $99 because it’s the sort of dishonest advertising that takes advantage of a psychological bias. I understand why Walmart does it, but that doesn’t make it a smart thing that good people do. It’s ths sort of deceptive thing greedy people do.
The marketplace probably matters regarding 99 pricing. On Craigslist it looks different than Amazon marketplace or eBay. I sold books on Amazon and all the big sellers used 99 but then when some college kid (with little or no feedback) listed a used textbook they would use a whole number. So, trustworthiness based on 99 doesn’t work that way on Amazon or eBay. The whole number listers are the ones with little sales history and no feedback for you to judge.
I personally use a nickel less than the dollar or $5 less than $100. If I want to sell something for $400 I will list it at $395.
