I've been reading a lot of old threads and it sounded like Adbuyer was a big resource for buying remnant inventory. But now when I visit the site, I get redirected to a login page on the mbuy.com domain ( no option to register an account).
Is Adbuyer dead? Is Sitescout now the only option for smaller buys?
I haven't used them in a long time. If their site is redirecting to another domain I guess they closed shop.
Adperium is one that you can make smaller buys.
They sold a while ago and haven't really been around for a while. You can buy remnant from almost any DSP these days like SiteScout, Adperium, Engage:BDR and many others.
