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.

This is the microwave version of the original. I cannot stand it. The noodles have no flavor at all; and to me it is not spicy. I will not order any more of this product!

The bonsai itself is fine.  You cannot immediately tell it's artificial.  It just looks like a healthy little tree.  That being said, I have pretty much an exact identical from a set of three I also purchased online here.  I could have bought another set of three with the money I paid for this one.  The picture used makes it look like a larger bonsai and is clearly not the one you receive.  Live and learn.
