One use for them is to obfuscate my banking information. A few years ago, Sony leaked a ton of Playstation customer information. Since then, if I want to buy games from them, i buy a gift card from someone else, and then use the gift card. It adds a layer of indirection.
Also for mental convenience. I use Spotify Premium. I don't want a recurring subscription charge that I would have to remember to cancel. So I go buy a year's Premium gift card (with a small discount on the monthly rate by doing so). If it runs out, I just get put back on the free tier with ads and no direct song picking until I get another gift card. They can't charge me in perpetuity, and if I ever stop using it enough for keeping it to be worthwhile it effectively cancels itself.
