I am looking for a reference on this topic. Every knows that the difference in cost between $100 and $99 is more than $1 in the minds of consumers. Thus prices ending in $99 are commonplace but obvious and somehow make the seller appear disingenuous.
Are there any other digit combinations that have relatively lower perceived cost?
For example, $187 seems not much more than $180. Is a price ending in 87 good for the vendor?
Ideally I'd like to find a chart with, say, 100 to 200 on horizontal axis and the actual perceived cost on the vertical. It would not be a straight line with, e.g. with a step up at 200. A chart like this would help fine-tune product pricing.
