"A hamster. Not just the hamster as those costed like $7, but the cage, the plastic hamster ball thing, the bedding, the treats- the works! I named him Sam. He lived to be almost 5 years old and he was the best. My mom helped me figure out how much money food costs and I made sure I had enough money saved at the time of buying him, to be able to get him food for at least a whole year. My mom didn’t think he’d stay alive longer than that."

Sure, I could afford to just buy it, but I decided to pay for this one outside my regular budget, so I set aside some money each month for a while. Just as I had enough set aside it became available and with a discount, so I'll probably get the kit to put lights in it as well.
I'll "set money aside monthly" more when I want something though; getting something you want feels better when you have saved up for it over time rather than just having enough money after bills to simply buy it.
