Amazon Flex does allow drivers to receive tips, although it is important to note that tips are not guaranteed with every delivery. This means that while you may have the opportunity to earn additional income through customer gratuities, the amount you receive can vary significantly based on factors such as customer satisfaction and the nature of the delivery. One of the appealing aspects of Amazon Flex is that drivers keep 100% of the tips they earn, meaning there are no deductions taken by Amazon. Additionally, drivers can view available scheduling blocks in their area through the Offers screen in the Amazon Flex app, which helps them plan their work hours effectively. Overall, while tips can enhance your earnings, they should be viewed as a supplementary source of income rather than a reliable component of your overall pay.
