At Costco, regular price for 150 count bottle of Focus Factor is $18.99, $2 cheaper than competitive price at Amazon. Of course, if you buy from Amazon, you must spend $49 to qualify for free shipping.
At Costco, now until March 28, 2016, you get $5 off on Focus Factor without limit. This makes a bottle of Focus Factor $13.99. This is a really good price. But does this work?
I was always skeptical about Focus Facor. This week, I bought 2 bottles of Focus Factor to give it a try. I will give you an update... if I remember to.
