, you'll have to explain the difference. Here is what I know, because I ordered some.
you click the link, it takes you to the Mr. Snuff website, and there is
some Samuel Gawith Gold Mull in a 10g tap box that is featured there.
That is currently the only snuff offered under this deal. You add it
to you shopping cart, along with whatever else you would like to order,
and then you check out. During the check out process you enter the
coupon code, and it removes the cost of the Samuel Gawith Gold Mull 10g
tap box from your order. You still pay for the rest of your order, and
you still pay shipping for your order.
Please let me know anything that remains unclear very specifically, so I can help get the answer."
The thread was closed so I'm answering you here.
When you say "Free snuff" that means you can get something for nothing. There are/have been offers like that, for example from Dholakia. You send them your mailing address and they send you a nice gift for free. Really free.
In this case I really don't know one way or the other if it is true. It depends on this: if you have to buy something, then it's not free. If you can just go to the site and enter your address and the snuff comes in the mail it's free. There is a legal difference between "Free box of snuff with a purchase at no additional cost" and "free." Now if it is really free but you only have to pay for shipping that makes it a little foggier. As it is it is not explained clearly. If you have to *only* pay shipping it could say "Free box of snuff for the price of shipping."
