Costco offers its members the Skyway 20" Softside Spinner Carry-On in Blue or Black for $29.99 plus $9.99 for shipping. (Non-members must pay a $1.50 surcharge.) That's $20 under the lowest total price we could find for a similar Skyway suitcase elsewhere. It measures 19.5" x 14" x 8", expands an extra 2", and features a retractable handle.
