I would give a giftcard if one were available. I'd buy a $30 card for $30. If one weren't available, I sure wouldn't pay a company $1.50 to set up a hoop for my friend to jump through.
You'd use the service. I wouldn't. I argued why I don't see anyone using it. Don't write me off as an internet misanthrope trying to ruin everyone's fun.
edit: I'll be more constructive. I'd consider using this if it somehow felt like a gift card instead of a deposit to my paypal account.
