Something similar happened to me. I tried using the Costco coupon code for Budget Car Rental (10-25% off). Initially I forgot to apply the coupon at the Budget website and got a weekly rental of $134. But when I did apply the coupon, the rate went up to $139. Had I applied it initially, I never would have known.
...
I ended up finding a better deal at National anyway. I never seem to have luck with car rental coupons.
I used to spend a lot of time trying every code I could find. I decided overall it wasn't worth the time or effort. In the end, it appeared the rental company had two or three different rates available, and each of the codes I would try would return gave one of those raes.
There are several codes that I use now that seem to work best for me (Costco, several Alaska Airlines, AAA, and a few others I disremember right now), but I still have to try every one every time. Then I still compare the results with what I'm offered without using any codes. And, after doing all of that, I check what kind of an offer I can get from Hotwire, and do some Priceline bidding at levels below the lower of my best rental company offer or the Hotwire offer.

Getting back to car rental company offers, the code or option that works best one time will not necessarily be the best at another time. Similarly, the company that gives the best offer one time will not be the best at some other time.
If you want to get a good rate, there is no substitute for simply working through the various options to see what you get. And you will often find that the first rate you were quoted may be the best.
FYI - I always start my search at a site such as Orbitz, where I can see the offers from several companies displayed side by side. The companies that come up with the lowest rates at Orbitz will usually (though not always) still be the lowest after working my way through various options (though the rates I end up with likely not be the Orbitz rate). It's rare, though, for a company to be the cheapest alternative after Orbitz showed them twice as expensive.

Another option to check is to see if you can contact someone who handles reservations at a local rental location without going through the main call-in center. There is often availability and rates available through local offices that does not show up in the National reservation system.
For example, right now I have a car rented from Budget on an itinerary for which Budget's national reservation system showed no availability. Further, when I checked the options through Orbitz, the cheapest offering was $65/day for a compact (high daily price because I'm dropping the car off at a different location from which I'm picking it up.)
By calling the Budget office at my pickup location, I was able to get a reservation for $33/day for a compact.
The "local contact" option probably works best at a location where the car rental operation is handled by a franchisee instead of by the car rental company itself.
