Input: Consider 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.

Input: Consider Input: I'm drinking oolong tea because Dr Oz said it would raise metabolism, the jury is still out.......really how would you know? I have lost weight but that's because I quit drinking coffee which I added too much cream to and started working out a lot more. It does not taste the all that great so I add 3 equals and drink it after it cools.
