For me personally it's fun to vary the intensity and the ratio of coffee and milk. After all, everyone has a different taste and has to discover his personal secret recipe themselves.
The set of 3 on Amazon is often cheaper than the store, especially in saving SUBSCRIPTION, as we have it.
For the Latte Macchiato is a coffee and a milk capsule needs (both included in the package).
Dolce Gusto capsules are not quite cheap, but extremely tasty and therefore worth the price, at least - for a ready-selling is more expensive ...!
And the fun is certainly not too short!
