I requested this sample on August 13th and received my sample on September 8th. This offer looks to be available again if you haven't had a chance to request one yet. By the way, this offer is not available for residents of Alaska or Hawaii as when I requested this sample earlier this year it never arrived.
I always find samples like these helpful. Here is a free Equate Ultra Thin Kit for you to request. It will contain: two Long Super Ultra Thin Pads and two Overnight Ultra Thin Pads.
Just go here and click where it says "Get Free Sample" in the orange box. A new window will open up with the form for you to fill out.
