Renewed is Amazon’s name for refurbished or reconditioned technology products or items. If you see a product inside Amazon that says “renewed” next to it, that product has been refurbished – this is why it is cheaper than normal.
If you’re in the market to save some money, buying refurbished tech – say a phone or a PC – is one of the quickest ways to do this. Compared to buying new, you could save anywhere from 30% to 50%, depending on the product.
I’ve personally bought several refurbished iPhones over the years and a couple of MacBooks too – one direct from Apple, the other via Gazelle.
But if you want the most choice, go with Amazon – it has more options for refurbished tech than anybody else. Not that this is surprising. This is Amazon we’re talking about here.
