I have several domains I've recently put up on 90 day auction on godaddy. Two of those domains I paid the $19.98 upgrade to have them shown on the featured listings. It's been several days to a couple weeks since I listed these domains, but no offers or bids. Is this cause for concern? Do buyers usually wait till later if not near the end of auction? Was it a waste of time to upgrade those two domains? I'm sure that quality of the domain name is the biggest factor in getting bids or sales, of course, but do even good domains sometimes take a while before bids or offers start coming in?
