I had the same thought cross my mind with a different set of sticks from another company. The problem was that a single stick was over half the price of the set of three. Knowing that I would like to have two sets of four sticks I went ahead and purchased another set of three that year, then purchased the second set the year after. I then had a set of four and a set of four/five. This is another way of looking at it if you are going to continue purchasing this particular brand in the future. If you can spread out the cost, you can seem to justify it a little bit more. Plus it is nice a have a spare set laying around in case you need to put one up in a hurry.
