When should I start to look for a rental I'm going in July?

I was just wondering when do they put out in any codes and where do I find them for when we go to Las vegas in July? Any help would be appreciated please.
A lot of the codes will come out a month or so before. That being said, if you see any decent rate, book it. You can always change or cancel as often as necessary. And keep checking this site for updated codes for the various rental car companies. https://www.carrentalsavers.com/alamo.html.
I already book a car for my June vacation. Lots of times I rebook 5 or 6 times as prices come down.
FYI: I've already rebooked twice. My rental came down $40, but today it's back up higher than what I originally booked. I check every day.

I agree book now and then re-check and look for discount codes if available. Last time my best rate was only 2 weeks out. And was very good. Glad I re-checked.
