The one you want to wait on is the link i posted above for true car because no matter what time of the month you get the code it expires at the end of that month. The one you sign up for from ramtruck.com like i posted above also is better to sign up now if you think your truck will be here within a month because otherwise you may miss it. They are not a for sure thing , some people receive them and some don't. And by the way the truecar code gets to you as soon as you click the link , you dont have to wait for a mailer. The ram one can be sent to your email or regular mail depending on how you sign up.I am confused because I see some people say to wait to request a coupon until it is closer to the time of delivery so it won't expire but then others say the dealer can lock it in anytime while you are waiting for delivery. I guess the two main ones I am thinking of is the $500 truecar and one that may get mailed or emailed to you from Ram. So is it best to wait until you are about a month out from delivery, or just do it now?
