The Good:  Walker shortbread cookies are my favorite, I love them.  I bought the highlanders and each set of cookies came individually wrapped with two cookies each.  If this were the end of it, a five star review.  The Bad:  Unfortunately, Amazon shipped them in a box that was about the same size as the container they came in from the Walkers cookie company.  After UPS was through with the shipment, my cookies were reduced to crumbs.  I contacted Amazon about this problem without ever receiving a response.  Since I bought these "Shipped and Sold by Amazon", I won't be purchasing these cookies from Amazon again.

My family is gluten intolerant and we use this product extensively.  Pancakes, biscuits, waffles, it doesn't really matter what you need to bake, this mix comes through.  This is my go to mix above Bob's and all others we have tried.  Try a box, follow the instructions for pancakes, and tell me they aren't awesome... go ahead... I dare you.

This coffee is a lot like the Green Mountain Nantucket blend.  If you like that, you'll like this.  Generally, the GM product costs less, but this was on sale.
