It takes more work, but eBay is definitely the safer way to sell a used MacBook than Craigslist or Facebook Marketplace. It also exposes you to a much wider audience of potential buyers, meaning you might fetch a higher price -- though you also have a lot more competing sellers as well.
Just be sure to take note of eBay's buyer and seller protection policies, which tend to favor the buyer in the event that, say, your MacBook won't boot or arrives with a cracked screen. In other words, sellers need to do their homework, too.
Amazon is one of the world's largest retailers, so it won't come as a surprise that it also stocks a range of refurbished items on the Amazon Renewed storefront. The company first set up shop as an online bookseller in 1994, before quickly expanding into all areas of retail.
Third-party sellers are key to Amazon's success. That's also the case with the Amazon Renewed store. The majority of the items for sale here are not sold by Amazon, but are inspected and refurbished by third-party sellers. Amazon implements standards, though, so you can still be sure any second-hand item purchased through this store will be in good condition.
