It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold.  I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you.  Or me, at least. I'd still recommend it, just don't OD the way I did.

<a href="http://www.amazon.com/gp/product/B001GCVLXG">Walkers Shortbread Highlander Shortbread Portion Pack, 1.4 Ounce Units (Pack of 24)</a> My family loves these! It's a great 'snack' to carry in the car or it's a wonderful surprise in a lunchbag. The flavor is so rich and pure...I forgot how wonderful these shortbread cookies were. And the price is nice, too...as well as Amazon.com. I love this place!
