This may sound tricky, so here goes. I got a quote for a compact 02 dodge neon for 2 days for 24.99/day using FVG code, for sept 4-6. Total was 60.and some change. I found out through trial and error the cut off for an addtional day charge was 45 mins. So i picked an 830 am p/u and a 915 am drop time. I was checking again today and just had it at 9 am pu and drop times and it went down to 58.32 total price. The taxes went down! I played with the 45 min window and only if i rented in one hour(such as 9) and returned the next hour(at 10) it went back up, even if only 15 mins later such as 945 pu and 1000 drop. Why would the next hour time be more in taxes??? Another strange one. Regardless, i rebooked for the same 'hour' time frame with a 45 min window for less.
