First thing about coffee is....... "ground coffee" will go stale pretty fast once you open the bag/container. Unless you are buying roasted beans and grinding in batches yourself, you need to buy in smaller quantities. Or if you want to buy ground coffee in bulk, you need to vaccum seal in small batches (I recommend about 2 weeks worth for each batch) and store them in a cool, dark pantry (up to 6 months) or in the freezer (longer than 6 months). Never in the fridge.
Ground coffee should be stored in an air-tight glass or ceramic container and once exposed to air will go stale in about 2~3 weeks.
For store-bought grounds I think Illy or Lavazza are the better options. Starbucks is also good too. Stay away from flavored coffees, and when in doubt choose beans/grounds with the word "espresso" on the label.
Hope this helps~
