Is this a good rate for National?

[frannn]

I am looking for at least a full size car for 9/10-9/20, renting from Orlando airport (may change to 9/9-9/20, renting from West Palm Beach, returning to Orlando, but that's another story). I was able to get 283.75 with the Priceless code (but 440.? using the second scenario-ouch!). If I add the Ent coupon (haven't bought the book yet), it goes down to 262.45. Is this great or should I expect better deals after the summer? I booked this in the meanwhile, of course! TIA!
