Do you throw away birthday/holiday cards?

I have a box full of cards that I’ve saved but I don’t even look through them, they just take up extra space. Though, I feel that if one of my family members dies, then I’ll have their letters and cards to have but I don’t know.

What do you guys do with these cards? I like the idea of keeping them for a little bit until throwing them away after the holiday or like a week later after a birthday but 🤷‍♀️

Edit: Thank you all!
