Being a recent convert to
ebay, I have noticed that too,
I collect the jam jar labels, Ajman and Manama etc, just because
in the main they were free, and always found as fillers
in stock books and accumulations.
On
ebay I notice they are generally around $5 each
I find this extraordinary.
I suppose it's a numbers thing.
Your vendor has 1500 lots approx, if he sells 1 a day overpriced
perhaps that pays?
What is the downside of listing so many?
