Ron,
ebay has no clue about selling collectibles, especially small lightweight items like stamps. I checked some old searches and found that many no longer work. Still, I didn't see "featured" listings. I did notice a continuing build up of unsold inventory. I guess if no one can find the stamps they want, nothing will sell.
It is too bad that Stanley Gibbons set the alternative stamp marketplace back about three years. Now that they are out of the picture, perhaps BidStart and HipStamp can make inroads into the
ebay marketplace. Alternatively, perhaps the APS will get around to finding better scanning and image processing software as well as more buyer friendly StampStore interface.
I have more or less given up on trying to buy anything on
ebay because I dislike their web site. I guess it could be get better or worse. It appears that
ebay has management has opted for worse. I could never sell on
ebay without third party software to minimize contact with their web site. I suppose a market could exist for software to filter out "featured" items or sellers to avoid.
