Just to confirm as of December of last Year Avaya discontinued the certification kit program.
My take (I didn't get the kit for my last two ACSs or my ACE):
If you don't want to send me the marketing materials (i.e. laptop bag, shirt, pin, etc), I still deserve to have a hard copy of my certificate. It's fantastic that I can print new copies as I feel a need to, but I still should get a single, hard copy from Avaya. And how much would that cost anyway?
I've voiced this opinion to Avaya. Hopefully they'll see the error in their ways...
