Use coupon code STARTUP1000P666 for $1000 CREDITS
Log into your account
Go to Settings & Members
Go to Billing, select Upgrade (I chose Personal Pro) and enter the code STARTUP1000P666
You need to enter a card to checkout.
You can also apply the coupon code: ADALOVELACE for an EXTRA $500 CREDITS! (Not working anymore)
***Another hack for Notion: Once you get all your credit, upgrade to Team Plan, then add code: HAPPYHOUR, get another $250 in credits. Then you can downgrade to Personal Pro
