I wonder if there isn't a "correlation =/= causation" deal going on there though. Guys with high volume sales would be more customer friendly and would do stuff like that, bending over backwards for customers to the extent possible even if only in a symbolic way. They would also have more professional operations so the percentage of returns would be lower than skeptical seller of stuff in his garage. I could be wrong though.
To my fellow sellers, one bit of advice if you weren't aware to protect yourself against problem buyers. On "Account" "Site Preferences" "Selling Preferences" "Buyer Requirements," you can restrict who can bid on your stuff. I use all of these:
Don't have a PayPal account
Have received 2 Unpaid Item strike(s) within 1 Month(s)
Have a primary shipping address in a location I don't ship to
Have 4 Policy Violation report(s) within 1 Month(s)
Have a feedback score of -1 or lower
Are currently winning or have bought 10 of my items in the last 10 days and have a feedback score of 5 or lower
