Anyone heard of directindustry?

Some how I cam across Optical Components - All industrial manufacturers in this category (In no way am I affiliated with them or promote them) and I searched the name "directindustry" with no results. I'm assuming they are for large vendors or large business, and that we muggles/regular people can't afford them?

Because I was looking at getting some stuff in the future and looks like there is heaps of stuffs to buy here... Maybe a group buy some time?

They appear to be a reseller. So I highly don't we would get any deals even with a group buy if they permitted. Good share, but probably a waste of time reaching them
