Example Input: Dried mangoes are my hubby's favorite fruit.  He especially LOVES the Philippine brand.  Some come close, but no cigar.  We have searched high & low to find a brand comparative to these, but there are none.  Having them delivered on a regular basis is great & with free shipping.  No more detective work and disappointment.  He does have to be careful however, because he seems to eat them too fast & runs out short of the next delivery, maybe I will increase my quantity!  Quality is the best.  Delivery on a regular basis was a perfect gift for him.  I am very happy & satisfied.

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: Excellent and tasty though I thought not enough garlic so I added more. When I order GARLIC I guess I expect more of it.  But perfect if you have guests as it will never offend anyone. Omaha always is sure to do everything to please their customers, a premier company, hard to find anymore.
