Good question but a challening task since there are so many retailers out there. Plus, you've got to factor in specials that occasionally come and go. What I've done over the years is built a list of retailers, who I do business with, and then I can check their prices whenever I have a question about what a cigar or box is worth. It's never an exact science, but it can get you pretty close. :smile:
The other thing to consider is are you buying on-line are from a B&M? The reason I ask is that I periodically stop by my B&M to have a PAM or some other tasty treat, and will pay a buck or two more for the smoke. However, I don't feel that I'm being ripped off since it's a spot that I can hang out in while I smoke and they have a store front to pay for where on-line retailers don't always have that same kind of expense.
