Sure, some looney dreamers are out there but I've also been able to access some great postal history material over the years (some with rock bottom prices to boot).
But, recently I've noticed that despite the free listings, if your item does not sell (repeatedly), eBay will continue to charge listing fees when it gets re-listed three or four times. Even if it does not sell. So, each time it is re-listed, eBay get their $$

Delcampe, on the other hand, only seem to charge listing or final seller fees if your item actually sells. In comparison, this seems so much the fairer.
What do other private sellers think about these fees?
Sure, these companies are out to make a considerable profit on the side. But, have you ever noticed how much you pay in fees for listing items over the years? Have you a preferred method for selling or listing your stamps, other than here on Stampboards?
