Well, they don't assign an arbitrary rate; if you book with promo code BCFD as you're supposed to, it actually doesn't change the rate from the regular retail rate.

Technically, a reservation that you use free day certificates with should have BCFD in the promo code field, so you're not really supposed to book with another discount code. That's not really enforced, IME, though, so yes, that might help. I rarely see discount codes for more than 5% off at Thrifty, though, so you'll be saving pennies, not dollars.
