Well, first, are you a CPST? That's the only way to get the discount. (I'm assuming you are, since you're asking, but just in case.)
Okay...I feel more ignorant...what's the extranet?
On the SafeKids website, you log in with your tech info to record your CEUs and stuff. Somewhere on there (can't remember now--in the online CEU section, I think) is the Britax extranet with the info about their program.
Saw another post where someone mentioned a 'Tech discount' I wasn't aware there was a CPST discount. I usually only frequent this forum if I have a question for a client that I can't find thru other research or if I'm looking for support from other like minded folk so I'd never heard of a 'Tech Discount'.
Just a disclaimer since you mention "clients." The Sunshine Kids program allows you to use the discount to purchase seats as demonstration seats only

. Britax allows you to buy seats as gifts, but you can't resell them. So if you were looking for a way to buy seats FOR other people, you can't technically do it under either program.
