Lots of roundabout searching on the internet for wholesalers has accidentally led me to Link hidden: Login to view (which I hardly ever use). I found that a search on 'wholesale and distribution' gave me more interesting leads to potential supply sources than looking at Google (my hypothesis: Google is maybe a bigger target for scammers as most people will look there first???).
Anyhow, these two search terms seem to be quite fruitful in terms of finding leads that might be of potential interest (even found WoList, which allows you to search the world for music overruns - of potential interest if selling CDs, for example, and much more).
Try these 2 terms on Gigablast, anyway. They might lead somewhere - you never know. I'm still trying to wade through it.
