Great product, nice combination of chocolates and perfect size!  The bags had plenty, and they were shipped promptly.  The kids in the neighborhood liked our candies!

I've subscribed to receive Pamela's GF cookie mix and after the second delivery of OLD mixes I am returning to buying them in the store.  All of the last mixes during the last several months (6 bags per order x 2 = 12) have been OLD -- not expired, but the chocolate is dried up, light brown and crumbles to a powder.  I discovered it's not possible to return a subscribe 'n save order (for some reason) so I have to throw out the chocolate chips and use Ghiradelli instead.  Whenever I have bought Pamela's from Whole Foods the chocolate in the mix has been dark brown, fresh and never has crumbled to powder.  AVOID subscribe and save on this item.  Buy them in a store.

My dog's breeder sent home a baggie of cheese and egg flavored Charlie Bears for my Maltese puppy.  I used them to reward him from the get-go, and he will do just about anything if he knows this treat is coming.  A great training aid.  They are also small enough to give often, and are made with good ingredients.  I carry them in my pocket and my little guy keeps an eye on that pocket!
