I posted the other day in the 'coffee' thread about a recent 3rd party, Nespresso compatible capsule by Caffè Vergnano
. They have Caffès in the US, I believe.
A box of 10 Espresso comes to 3.20 euros. We have only 4 blends in the range here in It. I got the Intenso and Arabica and they're not bad at all. Similar in strength to the Ristretto, Arpeggio or Roma.
