Mack Weldon is kinda annoying and wonโt give you a code without an ip address. On iPhone I had to go to Settings app and go to the Safari settings and scroll down to โhide ip addressโ and turn it off just to get the code from the Mack Weldon site (then you can go turn that setting back on right away and use that code at checkout)
Tesla is always changing the referral program so check their website for the latest perks. Latest is up to $1000 off plus 3 months of FSD ($200 value per month). And if I refer someone I can get a free acceleration boost which would be amazing
