finding purchase history is super simple. Just open the Amazon website, log into your account, and hover over 'Account & Lists' in the top right corner. From there, click on 'Your Orders.' You'll see a filter option—select 'Digital Orders' to narrow it down to your Kindle purchases. If you want an even quicker way, go directly to the 'Manage Your Content and Devices' page under 'Account & Lists.' There, you can sort by books, magazines, or apps, and it shows everything you’ve ever bought. I love how organized it keeps everything, especially when I’m trying to remember what I’ve already bought during a sale.
