Amazon has its AmazonBasics 20″ Hardshell Spinner in slate grey for $29.99 (regularly $59.99) with Free Shipping for a limited time.

The AmazonBasics hard-shell spinner luggage measures 20 inches–a size that’s accepted as carry-on for most international flights. The luggage also works well for weekend getaways or one- to two-day business trips, offering enough packing space to hold a few changes of clothes, toiletries, and a pair of shoes. It provides a durable zipper for reliable closure, and its expandable design creates up to 15% more packing space for extra room when you need it (and less when you don’t).
