I had a random one too, but they were a forum user and PM'd me about it. Thanks to all those that use codes they find here. Hopefully some of our content proves useful to you and aids in your buying decision!
Yup totally agree, would be great if Rivian provided info for thanking people for using your referral code. I am an owner since March of an R1S Gen 2 and someone used my code. What a pleasant surprise!
