I have three extra bottles, brand new, sealed, expiration date 8/1/2026 on all of them, though they're still safe after expiration, they just start to slowly lose effectiveness. One bottle for $15, two for $25, or three for $30.
60 pills per bottle, 2 pills a night recommended dose (though I find 1 pill a night works well for me). Since I don't take the full amount, I end up with extra bottles over time since I get this as a bundled combo monthly subscription.
