I just noticed this on my Facebook and am super excited about it. Starting tomorrow (9/17/13) at 3:00 PM EST, Munchkin will be giving away click lock cups to the FIRST 100 people who fill out the form. This will go everyday until 9/20/13.
However, if your unable to get one you'll also receive a $1.00 off coupon.
