The short answer is as a single person with a significant amount of expendable income, I buy a lot of toys. The long answer is I buy almost everything except for food off of Amazon. Need a couch, get it off Amazon, want a shiny new video game controller, Amazon, clothing, Amazon.
Now to be fair, 1,500 might be more of an outlier month, with the average month being closer to 900 or 800$.
I used to do this, but now I check aliexpress.com first - usually I can find things at a third of the price, sometimes 10x cheaper, and I haven't really felt a lack of quality (just shipping speed).
I got close to that after buying a house and filling it with whatever things I figured out I needed but didn’t want to drive to the store for (tools, cleaning supplies, kitchen stuff, holiday decorations, non food consumables, etc.)
I can’t see sustaining it indefinitely, but for a year or even two wouldn’t shock me if you’re not frugal and have a big empty house.
