Unless you have 100's of listings at anyone time now ebay is a very hard place to earn a decent wedge from mate, the fees and idiots have killed it!
Not so true,
I only have 58 approx listings active in my shop but its a specialist market im in so the buyers are there. I started when there was approx only 3 pages of listing so i built a reputation up. People have jumped on my bandwagon now but the reputation keeps us going and we find most ebay customers also end up buying direct in future. So its cheap advertising.
