I have always wondered about this. I buy and return a lot from Amazon. Do you have any further information? I've always looked to see but have never found anything myself.

Anecdotally, twice after periods of large purchases and high dollar amount of returns (because I was buying a lot of equipment and sometimes had to buy several of the same due to them coming faulty), I noticed same-day and next day shipping would disappear for a few months. I was never able to conclusively determine what the reason was though.
