Actually the price is the same when we add in sales tax (7%) and estimated shipping charges (6.5%) as shown in the cart and checkout pages. We did this for three reasons. The first was transparency as to what was being added to the retail prices as set by the World Service Office. Secondly is that it makes it easier for us when we have to do pricing updates. The third reason is that we can easily increase or decrease the estimated shipping charges if we are not breaking even.
