Walgreens has the 2 oz shots of this product FARR of $5 – the 30 tablet pack, marked on the shelf at $18.49, is actually ringing up at $4.98 and generates a $5 RR when you buy two.  If you take tryptophan or know someone who does, this is a great stock-up price – the expiration dates are early 2014.  If you have no use for them, they’re listed on Amazon for $40/3 boxes.
