Hi Latasha,
Welcome to the Disney Parks Moms Panel with your question! I was excited to see your question, because I am always looking for ways to save money! From my experience, I have found that merchandise such as Minnie Ears, Pins and Autograph Books are generally the same price online and at the parks, and depending where you live when you add shipping on to your purchase, purchasing these items online can actually be more expensive.
Shopping for these items while on vacation at Walt Disney World Resort can be so much fun. I find that the selection at Walt Disney World is way more extensive than what you can find online. If you would like to save some extra money for your trip, try purchasing
Disney Gift Cards in small increments over time and keep them until your vacation. That way you will have some extra money set aside for those items.
I hope you have a magical time on your vacation Latasha. If you have any other questions while planning, please let me know. I would be happy to help!
Stephanie
