I had a change of plans, and needed to rebook a 2-day rental for a Wednesday-Friday in July. The lowest rate on a compact was $52.99 per day! I'll save 20% with DC discount, but that's still $104 total for 2 days! I then went to Dollar and reserved a compact for $25.99/day - using the KISS code. I figure with tax it will still be about $40 less than with National! So - National won't get my business this trip unless their rates go down considerably!
