After reading all of the posts in this thread I have to wonder if the best thing for G&H, and possibly other manufacturers, is to drop tins altogether and just sell bulk. That would speed up and simplify delivery, take the headache out of finding a quality tin manufacturer and place the responsibility for handling the product once purchased and delivered squarely where it belongs, with the buyer.
Plus, there would be less waste with the used tins and all. Something to consider.
