I always round prices up that end with .9x. On Kickstarter when prices are $79 I count them as $80. Saving me that minor calculation makes me more likely to buy something, it simply removes an annoyance. Is that really un-normal?
Maybe the effect goes away if we walk away and remember the price as $80, though.
When I look at the price of a pack of gummy bears and it's $1.96 I am forced to think $2. Then I have to keep in the back of my mind the fact that if I pay with cash I'm getting bad change and then I think what am I going to do with 4 cents?
I may get overly annoyed by this but please list actual prices. $1.96 is $2.
When prices don't include tax I don't bother with the calculation so I don't even know how much it's going to cost. Then I try and spend all the stupid change people keep giving me and people are impatient that I didn't count it ahead of time. You know maybe I would if I had known what the price was going to be even a moment before I was being asked for it. In most cases if it wasn't out of necessity I wouldn't shop at any of these places.
