You should probably check the italki support site https://support.italki.com/hc/en-us or write to them at [email protected] Off the top of my head, I believe the thing to do would be to buy italki gift certificates — but again, it would be best for you to search the support site or to write to customer service. Note: I believe the gift certificates expire after one year (if not used).

You can send an italki gift card to that person's email address. https://www.italki.com/giftcards

Hello, Nadya. If I were you, I would contact the Italki site directly. You can reach the support page at [email protected]. Good luck.
