If it said "receive a free limited edition Hard Rock NCV chip", I'd have no complaints.

All pre-registered members will receive a registration package that will contain special offers from some of the convention dealers

I can guarantee you that the dealer I bought the majority of chips from was not going to change his selling price because I pre-registered

In addition we are planning to give all pre-registered members a ticket for a cash raffle to be held during the show

I didn't care about that.

Where in the notice should I have ascertained that a chip worth $100 was going to be given away?

Regardless, I did attend the covention. I think I should have been given the opportunity to get a chip. When it was announced on the bb that a HR chip would be given away, it was too late for me to pre-register.
