Terrific value. Effective performance. Saved lots of money.
For years, I purchased Smart Caffeine from Natural Stacks, 6 60 capsule bottles at a time on autoship, to get their best price of $15 per bottle.<br /><br />This new (to me) Caffeine plus L-Theanine product appears to be the exact same formulation, works just as well, can be bought 1 bottle at a time, contains 90 capsules,  is only $10.55 per bottle, and can be put on Subscribe and Save to get it even cheaper. Better deal by far.
