I don’t fully understand the Ebay economy. I DO know that people assume things bought there are cheapest when they are actually wrong.
For example, many USED graphics cards sell on ebay for less than a NEW one from certain legitimate websites.
I’ve often seen grahics cards selling for higher than a new one on Newegg.com.
How ebay sellers function is a mystery to me though.. I keep reading about people who have ebay businesses buying / selling for minimum 50% markup.
Of course nobody would publish which categories move the most volume + most profitable, but it would be damn interesting to see those figures.
