There was similar thinking in retail not so long ago when prices started to change from something like 3.99 to 3.77, for example. I don't see this so much now which suggests it didn't work out as expected?
Thus $15.20 vs $15.40
It's a great museum by the way.
Seems like there are cheaper ways, but maybe the price cuts back on secondary labeling or sell association, ultimately saveing personnel time, which ultimately costs less than those expenses.
It gives a feeling that they're slightly cheaper than the competition, I think. Even if the more significant digit is more expensive sometimes, people don't remember that part as much because it varies from day to day.
I'd wish Apple cut the crap on that, it makes them look like you're buying stuff from a used car lot.
You’ll never see decimals in a fancy restaurant for example.
