Worked in pricing for a big retailer, it 100% works and retailers don’t even like doing it, but it’s basically a necessity to get baseline sales. It’s WAY easier to have simple even number prices that calculate easily and get percent off sales and clearance prices that make sense. Really the only items you see it on are items competing with other retailers, so kraft mayo that every store has vs. A store brand soda you don’t care about volume on. The Mayo you better have $5.99 instead of $6.00 or it looks like you’re ripping them off. And even if they sell it got $4.99 it still keeps people thinking it’s a complex price difference rather than an even number they can compare more easily.
Because religious people have a lot more kids that non, so a bigger potion of people get stuck into a culture they think they have to conform to in order to keep their parents happy, also they convinced us sex of every kind was basically a crime against God, so we became sexually repressed enough to fall in love emotionally and not sexually. Not daring to even question our orientations until over a decade after marriage, parents die, kids grow up, we didn’t raise them to be sexually repressed or afraid of being authentically true to themselves, and having a sexuality, which conflicted with our increasingly hateful and intolerant religion of birth, forced us to be honest with ourselves, abandon a creepy death cult, and accept who we always were. We finally understand why the sex was so terrible, the whole marriage, neither of us was interested.
