Prodigy Hardside Carry-On Spinner Suitcase $28 and American Tourister Star Wars (Kylo Ren or R2D2) Carry-On $22.40 plus FS with Kohls Charge (Bundle and earn $10 kohls cash)
I needed a carry-on for myself and one child, so I bundled one of each, making my total $50.40, earning $10 Kohls cash as well.
Don't own Prodigy, but most reviews are good. I do own a Disney Princess American Tourister just like these two and it is wonderful. It has not only survived multiple trips, but is often used by my 3-year old twins as a mode of transportation and battering ram on occasion and is still going strong. I own other American Tourister luggage and they have a good warranty and I have had pleasant experiences with their customer service.
