Ooooh. Free Finish lemon sparkle detergent? My, me, aren't we fancy. Time to pop that pinky, eat a crumpet, and dig out my monocle.
They do a pretty good job of denying this if you've ever requested a Finish sample before, but it's fairly easy to get past. Just add some random letters to your last name and if you live in a house, say you live in Apt. 1 at that address. Worked for me.
