Ebay Stamps Sellers Are Not What They Use To Be Or Am I Mistaken?

Some other online stamp/postal history marketplaces - e.g. the Hip sites, Delcampe - have no listing or relisting fee at all, so a vendor can keep items listed as long as they might want without incurring additional fees beyond the annual store subscription cost. And stamps are small - an online inventory of 10,000 items will take up a couple shelves, no need to periodically clear out space in the warehouse :)
