I haven't had any issue with CampBX and have done a bit of volume through them, but never received any discount.
Sounds like that's an issue to me. Sadly yet another contradiction to their own website's written words. I'd call that a lie but, hey just my opinion.
I thought thye said to contact them for volume discounts...? I never contacted them, so maybe that's why i'm not getting one...not so sure it's an outright lie. I think you're going a little overboard spreading all this stuff about them.
