As of 2015, two of the most reliable sources to find reduced-price iPads are Amazon.com and the refurbished iPads available on Apple.com through the Certified Refurbished section. The age and quality of the item determine the value and discount.
Apple's Certified Refurbished selection offers iPads at very reasonable prices. These iPads were once defective in some way but have gone through an Apple Certified Specialist for repair; Apple then sells these iPads at reduced prices due to their imperfect nature. However, according to reviews on Apple's websites, consumers often find that these refurbished items are more reliable than new ones, as they have gone through thorough testing and maintenance.
Amazon.com also features a wide selection of iPads, and the company runs specials on a regular basis. Look out for holidays such as Black Friday, Cyber Monday and more for huge price reductions on these and other high-ticket items. Amazon.com also has standalone sales by category randomly throughout the year, and it sells new iPads anywhere from 10 percent to 40 percent below the retail price.
If you are willing to purchase a used iPad from an individual, you can find very good deals on online marketplaces such as Craigslist and eBay.
