I had ordered a case of fuel from Sig last October, which was never filled. Last week they said it would be "at least another month" before I could expect my order to be fulfilled.
This past Monday I ordered a case from "Ritch's Brew". It arrived on Wednesday! Great service. I cancelled the Sig order.
Ritch's Brew formulates fuel using volume rather than weight, just like Sig did.
