I had a "problem" with him the first (and only) time I ordered from him
There was a glitch on his website...I didn't order enough of something to get free shipping, but it still gave me free shipping
He simply canceled my order without telling me
When I called to ask when my order would ship he got fairly abusive, acted like I tried to pull a fast one somehow and made it pretty clear that I had not ordered enough to be worth his time and trouble.
Despite the fact that I never raised my voice or showed any emoition other than surprise at how he was reacting.
In my opinion it is more important how a vendor handles problems than how smoothly things run for simple transactions
All these...I never had a problem are less important than how they take care of problems.
At the time I was willing to give him the benefit of the doubt...maybe he was just having a bad day.....but over time I have heard other reports of him treating customers like crrap.
