Gordon's Notes Rents a Car

The struggle over price discrimination continues:

Gordon's Notes: Car rental: enter gold number, price jumps $200: The 'arms race' of modern pricing continues apace. I priced a personal 5 day van rental twice on Travelocity - once with no loyalty number added and again with the loyalty number.The price of loyalty, was a $200 increase. Yes, I would pay Avis for the joy of being a loyal customer.

To their credit Travelocity listed Avis twice after I entered my registration number, once at the disloyal price and again at the inflated loyal price.These days it is increasingly foolish to do any price negotiation directly with a travel related vendor.
