There are no plans or tiers, just one price. Every card is free to start, and collecting the first 8 messages costs nothing. Until a card is unlocked, the names of the people who signed are visible but the words and videos are held back, and the card cannot be sealed or delivered. Each signer can see the notes they wrote on their own device.
Unlocking a card costs 3.99 in the currency shown at checkout ($3.99, £3.99 or €3.99, based on where you are or the currency you pick). It is paid once. It opens up every message, removes the message limit, switches on sealing with the envelope reveal, and adds a print-friendly keepsake. One payment covers that one card for good. There is no subscription, nothing renews, and we will never quietly charge you again.
Adding a video to your own note costs 0.99 in the same currency ($0.99, £0.99 or €0.99), paid by the person adding it. A paid video is stored with the card and revealed with everything else when the card is unlocked. If a card is never unlocked, the video stays stored but unseen, and the small fee is not refunded because the storage and processing have already happened.
Sales tax is added at checkout where it applies. Anyone with the signing link can pay to unlock a card, not just the organizer.
