My husband and I were both looking at buying the same book at the same time on our kindles. For some reason mine was going to cost me $9.99 and his was going to cost $6.31. We were shocked, so we searched another book and that time mine was cheaper by around $3 and his was more. Why is that?
I was searching for a new kindle book and I ran into the same situation as you did. By using a diffrent computer and browser I was able to save 30% off of the price. This makes me wonder how often I have been the victim of differential pricing from Amazon. I dont disagree with making a profit, but why try scam some your customers?
