Newbie,
Don"t be afraid to start roasting your own.There is a book by Kenneth Davids called "Home Coffee Roasting-Romance and Revival",its loaded with information on buying green coffee, the roasting process,brewing ect.I paid $1.50 at a second hand store for my first roaster(a poppery II popcorn maker)that still roasts a mean bean.
You will will find that after about three attempts,you will be roasting some pretty decent coffee,for about 1/3 to 1/4 the cost of the brand you mentioned,and before long you will be roasting coffee comparable,no,better than $tarbuck$.
Remember,nothing tastes better than fresh roasted coffee!
