I just got my GSSF cert in the mail. It says it expires on 4/1. I'm guessing this mean I have to use it buy 4/1? If not I'll use my membership card and I'll get the new pricing...? Also, the dealer told me that if I use my GSSF cert that the gun has to be ordered directly from Glock and I'll have to wait for it. They said they use to use guns from their stock but had issues getting the credit for them. Have other people seen this before?
