Seriously, there’s no way they didn’t choose that shit on purpose.
They do odd incremental pricing with a lot of things. I don’t know that it’s nefarious so much as it is nefarious. They know $14.99 is read by consumers as $15. $14.98 is a ratfucked $14.99. By the 0.80s we see it as $14.xx and it’s perceptibly cheaper.
At a few of my retail jobs, the .xx system was shorthand for pricing types: .95-open box, .90-clearance, .97-manager’s sale, whatever. Doubles are just easy on the eyes, too.
It can also be an item that’s 14.89 at another retailer and they want to be able to claim they have the lowest price
