Ex 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.

For those who love salt and vinegar potato chips, this is the one to choose. The flavor is zippy and tart, with no unpleasant chemical aftertaste like the less "natural" versions of this snack. The 2-ounce bags are just right to share at lunch. The chips are a little greasy, and that's why I've given them 4 stars instead of 5.

i have enjoyed this product for quite some time.  however, i am disgusted by the fact that the price keeps increasing!  at $35 per case, customers are paying more than $4 per box for 5 small cookie bars - ridiculous!  i will find a healthier, more reasonably priced snack to munch on. shame on nana and amazon. . .
