Bought these out of date (August 2022) but I knew that before purchasing as that information was stated. 96 cents a bottle - a complete steal and even though Melatonin loses efficacy over time these little tablets shore due work a treat. 30 minutes in and i'm yawning non stop. Bought 5 so will last a long time. Wish I bought 20...*
