After Moniker and SEDO, here comes Snap:
SnapNames, the most popular expiring domain marketplace, will begin auctioning off domains that aren’t expiring.
Expiring domains sell for a premium at SnapNames, thanks to auction frenzy. Domains that receive little attention while they are registered suddenly sell for $10,000, $20,000, or more. SnapNames is efficient and it’s much easier to buy domains at SnapNames than to individually contact domain owners before domains expire, even though you will likely pay more to acquire a domain at SnapNames.
