Avis - Any recent free LDW code out there

I am renting a 12 passengers van to drive teammates to an away game. I always use my Visa as my LDW inurance but since it is a van I decided to check and sure enough Visa only covers vehicle with up to 8 passengers.

Anybody knows a legit code I could use to get LDW for free?

My group has a negotiated rate, which includes free LDW, PAI, PEP, and ALI. Send me a PM and I'll hook you up with the details.
