Example Input: I have placed two orders for the weber grill grinder roasted garlic herb in the past.  I was so disappointing the last time I picked up my order as it was not what I had ordered.  It was citrus twist with garlic.  I just love the garlic and herb grinder and have given my first order away to my family as Christmas gifts.  I now don't even have one bottle for myself.  You can see I have reordered the garlic herb and hope I will receive what I have ordered.  It would be so inconvenient to repackage and return.  If it was possible to buy it in my location I would but it's not available.  Very Disappointed  Leona  The order that I received with the citus garlic was as follows.

Example Input: These are so nice and creamy!  Usually I don't justify buying k-cups for things like cocoa that you can get cheaper in a packet, but this is so convenient and very good tasting .. way better than most powdered cocoa packets I've tried.  As far as price comparison, it is equivalent to gourmet-types of cocoa that would easily cost $1+ per packet.  I also like that it comes in a variety pack with 3 flavor options.  Highly recommend
