I've tried a lot of different K-Cups and this is the weakest K-Cup coffee I've ever tried. It should not be labeled "Medium Roast", it should be labeled "Warm Water Tasteless" Roast. Too bad I bought a large box. What a waste...

Ex Input:
DOP San Marzano canned tomatoes are the finest canned tomatoes on the planet... but I can get these for literally half the price at my local grocery store. Is this unusual? Boston is pretty heavily Italian in some areas... maybe that makes a difference. i don't understand why anyone would buy them at this price. Check your local grocery store before you buy them at this price.
