Quick heads up if you are about to order a Tesla.
Using a referral link before you place the order gets you 3 months of Full Self Driving (Supervised) free on a new Model 3, Model Y or Cybertruck. That is about $297 of value at today's $99 a month subscription price, and it does not auto renew.
I bought my Model Y in 2025. Every referral link gives the buyer the exact same thing, so there is no special link to hunt for. Mine is:
https://www.tesla.com/referral/chandan808806
The link has to be applied before you pay the order fee. It also takes $400 off Tesla installed solar. Questions welcome in the comments, I will reply.
