What Mark said just above this post.
If one can get their hands out from sitting on them long enough to place an order with JR Cigars, a total shipping charge of $4.50 gets them as many tins of Dunhill pipe tobacco as they want. JR's shipping doubles after the current promotion ends (end of May IIRC).
CALL THEM -- don't order on line -- 1-800-JR-CIGAR ... that way, you'll be able to verify which of the Dunhill pipe tobaccos they currently have in stock, order as many as you want from that list and, unless you live in North Carolina (or Maryland), get it all shipped to you tax free for $4.50.
BTW, JR's latest catalog (2011 #3) lists six 50g tin Dunhill varieties, all priced $9.95 or $10.95.
