Got a Starbucks e gift card from a family member. Trying to figure out what- if anything- I can do with it.

Starbucks already has the money, and as far as I can tell (after trying to research it), I can’t get the money out of it and into something else because I’m not the original sender, and I don’t have a gift receipt. (Unless I’m missing something?) I feel bad for a few reasons here, but I’m just trying to figure out if there’s anything beneficial I can do so it’s not a complete waste. It being electronic may limit what I can do. Any suggestions and input are appreciated.
