If you buy regularly from Campos like I do then this may not be as much of a perk as it seems, but if you're wanting to give them a go then this is a good incentive. They have one of the nicest decaf blends around that actually has some flavour and body. They believe that decaf does not equate to wimpy.
Buy from Artisti Coffee, free delivery for me over $25 and the coffee is excellent.
