Don't do anything.
My mother is a total technophobe. She has no email address. She barely knows what the internet is, outside of "That thing you and your father do all day".
And yet she gets this...
Three high-quality glossy postcards, for Star Ocean TLH, Kingdom Hearts 2, and Final Fantasy XIII, show up in the mail, addressed to her.
She certainly didn't sign up for anything; not only would she not even know where to begin, but -I'm- signed up for all their "Yeah, you guys can send me free ****; I'm cool with that" offers and I didn't get them... she did.
She was gonna throw em out but told me "I kept them in case you wanted em, cause they look like something you might like."
