My son had this Jablum roasted and ground coffee brought back from Jamaica and paid a lot for it.  I have drunk blue mountain for years when I can but this was shocking.  It tasted stale when you opened the bag and even worse when you drank it.  It was definitely off.  He bought 5 bags and every one we tried was the same.  I would never buy another.  We had bought another brand in a tin from Jamaica which was fine.  I think this is a con.  You get all the rubbish about it being tested in Jamaica, well I dont know who tests it but definitely not someone who likes good coffee.  I just dont understand how people say its any good. Maybe having paid so much for it its like the emperor's new clothes.

My father could no longer take care of his beloved 6 year old Cocker Spaniel, so I decided to take her into my family. When I brought her to NYC she had ear and eye discharge. She was also  slightly overweight. After a check up with a vet that ruled out infection, I decided to try Royal Canin based on the numerous good reviews.Within a week her ear and eye problems were gone and she dropped a good amount of weight. This is going to be the only food that we will be feeding her!

This is the best tasting cracker I've ever tasted.  It may cost less in a Filipino or Asian store ... which is all well and good unless you don't live close to one (I don't).  Note that the box says 1 pound 14 ounces - but the description on this page says "28z" (whatever a "z" is).  If they meant "oz," it's incorrect.  It's a 30oz. box.  In any case, I was able to find it even cheaper online than the price shown on this page.  Where?  Amazon (grin).  Whenever you buy stuff like this, be sure to consider the "bottom line" price (product plus shipping) - and check for alternative Amazon pages where it's cheaper.  On this page, it's $15.78 for a 30oz box with free shipping (if you total order is $25 or more).  But on this page:  <a href="http://www.amazon.com/gp/product/B0066D2XVY">SKY FLAKES CRACKERS 1x850G</a>  the same 30oz box costs only $9.00 + $5.49 shipping ... or $14.49 total, over a dollar cheaper than on this page.  So, buy from Amazon ... but not from this page.
