Nice find -- thanks for sharing.

I tried a couple of the coupon codes on an upcoming reservation and they didn't error out, but also didn't lower the rate of the reservation (but I think that's typical of their reservation system -- the discount, if available, will be reflected at pick-up).

Just for kicks, I plugged in the BCD number listed for Cendant employees -- gave me a rate that was over $20 higher than the standard budget.com rate. Sounds like some of the supposed employee "discounts" at my employer!
