Different situation here. When Plaid (now Plaid+) was announced during Battery Day on 9/22/2020, orders were opened with a $1,000 fully-refundable deposit for exactly the same price as it is on today’s order page, except FSD is now $10,000 whereas it used to be $8,000.
Someone canceling a Plaid order that was placed in Q4 2020 and re-ordering the Plaid+ as a new order after the 01/27/2021 earnings call will not get a $2,000 discount, and will likely have to pay $10,000 for FSD.
The $2,000 discount is only being offered to those who ordered a current-at-the-time production vehicle (e.g. non-Plaid+ Model S) prior to the earnings call, but has not taken delivery yet. This is to offset the $10k+ jump in price from the former LR or Performance models to the new LR or Plaid (non-plus) models.
