I have been selling on eBay since 2001 and I have over 1100 feedbacks and no trouble at all. I haven't had any problems with paypal either.
I hear different horror stories now and then but I honestly haven't had any trouble. I don't sell much these days because of the increased fees. My ebay fees and paypal fees combined amounted to 20% of my gross last year. Way too much, if you ask me. But, as I said, I haven't had any problems in the 5 years I have been selling.
More power to you, and I'm very happy to hear you have had no trouble.
I had a bad experience, it cost me a lot of money and so I will NEVER say a good thing about them.
And I have never been mugged or been a victim of a car jacking or identity theft. That does not mean there is not a risk. Just because it has not happended to you to not make it a legitimate point that there is not cause for concern.
There are more than enough horror stories going around to be concerned.
To demonstrate how vulnerable you are, how about you FReep mail me your ebay name and I will see if I can get into to you for some free merchandise?
