When you look at the cost of a proper double espresso it's usually at least £2.00, so one a day is over £700 a year, that would buy a decent bean to cup machine.I imagine you need to drink a lot of coffee to justify the outlay......and maybe the faff of preparing and cleaning ??
I have/had** a Tassimo which suits me as I have just one per day and that is a "long" one eg Americano with milk.
**it stopped working
Got onto Bosch who reckon it could be a dodgy batch of pods but I am not sure.
I have two doubles a day, which is about £3.00 a week in beans, so relatively it's not that expensive.
