Interesting study to look into:

Online Shoppers Take a Day and a Half to “Buy Now”

[…] Slightly over one-third (37%) of shoppers took more than 12 hours to make a buy decision. Twenty-six percent took more than three days, with almost five (18%) of these “cautious shoppers” taking one week to decide where to buy.

This reminds me of the info overload effect (I can’t recall the name of the study) that online media produces. Not only will it be hard to pick the right product from the vast variety out there (try looking for the right cellphone), but you will feel the regret of making the wrong choice even before purchasing.

Makes you wonder, doesn’t it.
