Ex Input:
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.

I recieved a Keurig K-Cup Brewer for Christmas with sample cups of coffee and tea but no cocoa so I tried this brand and I like them but I haven't tried other brands yet to compare with. I would buy these again until I find one I like better.

I bought this because I was craving dark chocolate, and thought mint sounded great at the time. The chocolate is way too sweet. Dark chocolate is supposed to be a little bitter, not too much, but enough to give it some bite. I guess Ghirardelli decided to cancel that out by adding more sugar. Add to it the super sweet mint filling, and I could barely finish a square it was so sweet. Considering the expense, I expected a much better quality.
