Solid color MagicBands are $19.99. Premium MagicBands start at $29.99. MagicBand+ are even more expensive.
The cheapest option ($10) is to purchase a plain colored traditional MagicBand before your trip.
MagicBands are for sale up to 10 days prior to your arrival at Disney World. MagicBands may also be purchased at your Disney World resort when you arrive.
To get your MagicBand prior to your vacation you can order it online via your MyDisneyExperience App or from Shop Disney. You can also log into your Disney account on a computer browser.
An Apple Watch or Android watch can do many of the same functions that a MagicBand can do. You will need to utilize “MagicMobile Service” via the Disney app.
