This is a very broad question, I have read that it takes same efforts to convert $5 & $10. In that case how much does .99 help in today's online services.
It can have different results for business products and consumer products. I find .99 little messy and feel somebody who is ready to buy is not looking for 1cent discount.
However I can be wrong in many ways, does anybody have conversion metrics taken recently?
- What are the pros and cons?
- How is it different for consumer and business pricing?
- Who are the target audiences who will be affected by this change?
