You can order the same products online from Nespresso for approx $25 AND you can specify exactly what you want to buy rather than taking a mixture of items, some of which you may not like.  Nespresso makes GREAT coffee and GREAT machines. The Nespresso capsule offers posted on Amazon however are all by third parties who prey on people who don't know better.

I don't know how they did it - but this is by far the worst tasting carrot juice I have ever had.  I think it has to do with the long shelf life - expires in 2012, I drank it in 2010 (well I tried to drink it).  It was probably bottled in 2007 or something.  YYEECCHH!!
