I think the notion that reloading is cheaper is part fallacy and part depending on how you look at it. Given what it can cost for the components AND tooling/equipment, it can be quite a bit more expensive than buying off-the-shelf. Carefully done, such as buying major items used can help moderate the setup cost. If you roll all the costs of setup into it, if you are a low volume reloader, it can take a while to break even.
For me, when I only recently started reloading, I was excited because I had inherited much of the equipment. But, my penchant for high quality tools and equipment quickly cost me quite a bit, which I am not concerned about recouping. It didn't take long for me to realize the real benefit of reloading was quality control in the production of highly consistent ammo. I came to a point where I wanted to minimize all the physical variables/factors that contribute to inaccuracy in shooting so that I could learn to shoot (better). I want to be confident that the fliers on target are due to me rather than what I'm shooting with.
