Every weekday at 11am ET, supplies refresh for these free Mack's soft foam earplugs. There's Ultra, Snore Blockers, and Dreamgirl samples to choose from and you can expect your freebies in a few weeks.
Some days they run out of sample ASAP, while other days they never run out. It's pretty hit or miss, but as of right now it appears they still have some available from the previous days' release.
They've been offering these freebies for years now. I try reminding people of this offer once or twice a year, so consider yourself reminded!
