So I wanted to show you a seller I have been following for several YEARS (yes years!). They are STILL doing over $5k per MONTH in sales. And I guess they get repeat biz, they have a nice website (outside of Ebay) and seem to be doing pretty well.
Oh and there are other sellers in this niche - so they are not a one off
They have consistently made sales in spite of the recession. I hope you find this informative and can see there is still money to be made on Ebay and in Public Domain
