I really want to get into this more and get some different foreign MREs but after having Canadian vendors refuse to ship to the US and now these two UK vendors both shipments got rejected by customs....I don't know what to do next. Bummed out.

Are they any things we can do to help the vendors out? Like maybe tell them to put the rations inside another box (that doesn't say MILITARY RATION on it).
Maybe, on the customs form put military memorabilia (not for consumption) instead of food? Maybe that something sold as memorabilia is NOT subject to the same restrictions as food imports/exports?
I'd like to focus on ways to help make international shipping of MRE's easier for all of us.
