I've done it both ways, with taxes and shipping, and without either. I may have even done it with one and without the other, don't remember exactly. I think my logic when doing it without taxes and shipping is that those two items are going to be roughly the same, on average, for all sticks, depending, of course, on your local tax jurisdiction and on how many other sticks you ordered at the same time. But it's still going to average out, or at least I found it did, to be roughly in the 30 to 40 cent range per stick. So, it made sense, at least at the particular time I was using this logic, to drop those items and just enter the base price that I paid for the stick. I don't think there are any hard and fast rules for this so just go with whatever makes sense to you.
