I'm honestly astonished they don't require payment info on file to collect them by this point - initially it's a way to bribe people into making an account, and now they could bribe a bunch of people into giving payment info and lowering one more barrier to actually buying from them.
That's some dedication! Sometimes I wish I would do this more often. I start doing it, then it just fades away... Might be because some of the games don't apply to my taste, then I forget to keep up with it.
