Some used calculators come with extras like a protective case, USB cable for connecting to a computer, or a user manual. I considered these accessories a bonus and factored them into the overall value.
Price Comparison
I compared prices on various platforms like eBay, Amazon, and local marketplaces. Keep in mind that prices vary depending on condition, model, and included accessories. Setting a budget helped me avoid overspending.
