Will Disney Movie Club keep sending me mail?

Today in the mail, I got a letter from the Disney Movie Club saying welcome to the family.... and they have this offer where it's 5 DVDS for $1.99 each. I don't remember signing up for the Disney Movie Club and I was wondering if I don't respond to this mail, will they just stop sending me mail altogether? Also do they have like credit card information or anything of that area?|||No they won't. you probably bought something from disney online %26amp; got on their mailing list.
