EDIT: This is no longer available. It stayed up for a whole hour though!
The free Excedrin Extra Strength medicine I posted two weeks ago is available again. Let's see if it stay's up longer than 20 minutes this time.
As with other Sam's Club freebies, you don't need a membership number – just skip that field and the form should submit just fine. If you signed up for this freebie earlier, you won't be able to get it this time around.
