Amazon cuts up to 60% offDisney apparel, shoes, toys, and more. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to bag free shipping; otherwise it starts around $6.) A couple best bets:
The Disney Store offers the Darth Vader Rolling Luggage Case for $27.96 plus $7.95 for shipping. That's $12 off list and the lowest total price we could find. It features light-up wheels, a 3D sculptured mask on the front, retractable handle, and top carrying strap.
JCPenney offers the Disney Collection Planes 2 Travel Carry-On Luggage for $19.99. Opt for $3.95 in-store pickup to avoid the $8.95 shipping charge. That's $10 off list price and the lowest price we could find. It features a retractable handle and top carry strap.
