Give someone a year of never forgetting
It is a strange and very good gift: the person who always means to send a card, and never quite does, gets a year of cards arriving before they’re needed — addressed, stamped, ready.
You pay once. They add their own dates and their own addresses, so you never see their address book, and there is no card on file and nothing to cancel. When the year is up it simply ends.
The code doesn’t expire, and their year starts the day they use it rather than the day you buy it — so an early present wastes nothing.
