I have about a dozen low value domain names that I've had for 6 years or more. I hosted blogs using them at one point but I just want to get rid of them now. My guess is that they're not worth more than $10-$20 each so I think flippa is out for selling them due to the listing charge. Is there anywhere else I can do this? Otherwise I'll just let them expire.
Flippa is the best option....sell them in bulk. If they have anything in common sell them as a "niche group" if they don't just list them as "Bulk Domains"........ OR Use godaddy domain auctions, it's $5/ year for unlimited domains.
I wont recommend Flippa for small domains as they have huge listing fees and people there are looking to buy money making sites or domains so its useless to list it on Flippa. Try listing them here and you would surely find quick buyers the other best option I feel is namepros they get fastest sales on low value domains as lots of resellers are there to buy domains regularly.
On Flippa you can put too many domain in one listing so you won't be paying extra for this.. good for listing bulk packages.
