I read everything you wrote, but responded only to your reply to my post.
I have no international business experience either, but I ran the fulfillment and shipping department for a high end men's fashion shirt designer and manufacturer that covered the US market, and boy, was THAT an eye opener. It's war out there.
G&H lost their tin supplier, and got stuck with 500,000 tins that I'm sure they would rather not have had, but needed, and no mid sized business is in a position to dump that expense with no replacement. It's those tins or no shipments.
Of course, if someone here wants to buy them a half a million replacement tins that seal tightly, I'm sure they would use them.
The tops on the tins I bought a couple of years ago, with the shrink wrap around the join, will come right off. People can either whine about it and let the contents dry out, or deal with it by transferring the contents to a container better suited for long term storage. This is one of those "it is what it is" situations. One may not like the tins, but at least you got the tobacco.
In another thread on this matter I suggested, half facetiously, that they should drop the tins altogether and just go bulk to save money and problems. Went over like a lead balloon.
