Buying a used iPad is a great way to save money, but when buying a used product, there are a few things you should know before you buy it. You also want to get a good deal on the iPad, which means choosing a model that isn’t outdated and is reasonably priced.

Here are the main things to look for when buying a used iPad:

Flipsy.com tracks the average prices for used iPads on eBay, Amazon, and a few other online retailers. Used iPads typically go for about half to a third of their original value. If you’re buying a newer model, check the price of the newest iPad to see if it’s worth spending a little more for a warranty. Used iPads usually don’t come with a warranty, but some refurbished ones do.

A refurbished iPad has been returned to Apple and repaired. When you buy a refurbished iPad from Apple, you save money and, more importantly, you get the same one-year warranty from Apple as a new iPad. However, you may be able to buy a used iPad directly from the owner for a lower price.
