Didn't read the article yet, but I tried this: 2 euro vs. 1.99 euro and it made 0 difference in conversion rates. I guess it depends on the product. Maybe I should repeat the test, too.
That's impressive. Unfortunately the source* of theses number is not very clear on how many items has been sold and if people buy by unit or by pack. I would love to see more tests result like that.
Converison rate of 1.99 --> 5.2%
Mind = Blown. I mean, I knew the *.99 affected the consumer perception about the price, but not in such a huge way... Fantastic article (and blog).
PS: The "leaving know" modal is annoying, I was just trying to switch tabs
