I'm so dissapointed these are unavailable right now! I LOVE these crackers with cream cheese - it's my favorite snack! I hope they become available again soon! I can't find them anywhere!

I am fairly certain this is the same tea sold by Caribou Coffee.  I think I could be considered an addict! The flavor is so good - lots of cinnamon and slightly spicy because of it.  Price for 50 is good and less than I have been able to find it elsewhere.

This is good popcorn, I have purchased before in Hawaii.  I was happy to see that I can order online.  However, I purchase the 20 pack and they overstuffed the box.  There is no bubble wrap or any type of wrapping around the individual packages before they put it into the box.  They choose a small box that can barely fix all twenty packages.  It is overstuffed to the point that the box is no longer squared, but rounded somewhat.  The postal service does not treat the package with care, so when it arrived, there was a wet stain.  When we opened it, two packages had been damaged, and the butter leaked all over all the other packages.  We had to spend a long time washing all the packages, because they are all greasy.  The greasiness does not wash off easily even with soap.  Now when eating them, some of the other packages of popcorn got water in them because of the washing, they are not air-tight packages.  So when popping them, there are a lot of unpopped kernels.  They should use bigger boxes and wrap it better.
