Ignore the card
Valentine’s Day cards are now very expensive. So, instead of spending more on one, you could make one on your own. You would not need to be super creative. You could just create one with a cardboard, by cutting out love quotes that interest you from newspapers or magazines and attaching them on the cardboard. You could simply attach photos of you and your partner, and comment with the location in which the photo was taken and how much the photo means to you. This will not cost much but would definitely wow your partner.
