If you have any leftover money to spend on, there’s an opportunity to do so on December 30th. Amazon is doing its Amazon Digital Day sale, where loads of products, including video games, will be available at significant discounts. Hundreds of video games, in fact, will be on sale by as much as 80% off. It’s likely that Nintendo products will be among them, so be prepared for a lot of discounts in the next 24 hours. The sale will only last 24 hours, so if you want to buy anything, you’d better do it quickly.
