I disagree, I think it's detestable. As I said before, if someone has the patience and self-control to age the tobacco themselves it is worth the price premium AND they deserve to make the few bucks that they do. But by buying up and selling a tobacco that is not discontinued, exceptionally rare, or "collectible" not only are they abusing the tobacco rules of eBay, but they are doing the whole community a disservice (not to mention I doubt that seller is a licensed tobacco seller so laws and regulations go out the window in this case, but I could be wrong).
On a side note, if flipping a small quantity of tins is how someone intends to support their family I would recommend for them to get off eBay and pick up the employment section for a much steadier and higher-paying job choice. Of course I can't rewrite the laws of economics so as long as there is someone willing to pay that ridiculous bill then people like this will always be around and it will only get harder for the rest of us to get low-stock tobacco for our own enjoyment.
