I purchased my Ram Jan of 2020, just prior to COVID and used a bonus 1k off the price offered through USAA. To insure it wasn’t worked into the price I negotiated and when I sat down with the finance guy whipped out the certificate. While they were none to happy, they honored it.
So if you are a Vet or immediate family member of one you may want to search to see if this is still offered. I believe they also have a car buying service that affords discounts and eliminates the haggling (as mentioned, haggling may be a thing in the past).
