Whoa, the classic free Huggies Pull-Ups offer has returned today! The last time I posted these was in 2010 when Costco was giving them away. Man, remember when Costco, Walmart, and Target used to give away freebies on a weekly basis? Good times.
Anyways, go here to request the boys or girls version of either Pull-Ups Potty Training Pants or Pull-Ups Night*Time Training Pants. The signup form is a little weird – you have to click the gender's box, but don't click the text links inside it or it'll take you to the store. Just select the box, then click the purple next button to access the signup form.
