Not sure if there is a retailer in the Americas.
However, Giuseppe has sales quite often. In fact he was one right now...
"From the 1st of July till the 11th of August I offer a 20% discount on the order of ordinary bags superior to 50,00 euro (the order is valid for all of the ranges but is not applicable to FOG/Impetus and Regimental bags)."
Very nice figures, they are.
