Don't know of that company Alberto, and the shipping rate sounds exceptionally low. When I've sent an 'average' sized kit (smaller package than 1/32nd scale) to Europe, the cost has been anywhere between about £4.50 and £7 - even a small packet costs more than D-9 are charging.
When the new Revell kit is released, which must be very, very soon, at £19.99 in the UK, approximately 23 Euros, if it can't be found in Italy, then shipping from, say, the UK, would be around £5 to £8 maximum at a guess. So if shipped from the UK, probably a total cost of around 32 Euros. Externally, it's virtually identical to the G10/G14 anyway, being a 'late' G-6.
