I have 25 PIC Envelopes available. These run about $20 retail. They're all new - I'm just not teaching any more. If you want all 25, I'll sell them for $150 (that's a mere $6 per envelope) - great for your bottom line! I also have 8 Discover Scuba Registration Forms for $2 each (retail $5-6). If you buy all the PICs, I'll throw in the Discover Scuba forms! I will need to see you Instructor certification card.
