Sta-kon pricing is based on volume, even for authorized distributors. Just because a distributor is authorized for T&B in general doesn't mean they buy enough volume of terminals to get good pricing. The trick is to find one that does a lot of business with control panel builders, especially those serving big companies that will drive them to use only Sta-kons (as you have apparently found). One way to do that is to go to ABBs website for T&B and look for the rep agency for your area, then call the rep and ask them which of their distributors buys terminals in the highest volume in your area.
