Welcome to being an adult.
It sucks but knowing that you will have the money later to spend on a larger purchase is something I wish I knew back when I was spending 31.78 for Anime DVD's.
P.S. this was the early 2000's, we only got 3 to 5 episodes on each disc.
Hey, use the money the way you want to. You want to save it? You do you. No shame in that. Also gatcha is of the moment. Savings lasts ... umm... inflation eats it. But at least you're trying!
