“I discovered my 'expensive' boots actually cost less per year than the cheap ones I kept replacing. BuyItOnce changed how I think about purchases.”

“Finally, a tool that doesn't try to sell me more stuff. It just helps me understand what I already own. Exactly what I needed.”

“The warranty reminders alone have saved me hundreds. I caught a laptop issue 2 days before the warranty expired.”

Purchase price lies.
You know what you paid for something. But do you know if it was worth it? Most people don't track ownership over time. Receipts disappear, warranties expire unnoticed, and when something breaks you're left guessing whether it failed early or lasted well.
