Hi, Melanie!
Shopping in Walt Disney World is so much fun! Maybe TOO much fun, but who can resist! You will definitely want to set a budget for yourself as you can go mouse-crazy with all the great merchandise.
The cute Mickey plush start at around $20 and go up from there. Mouse ears start at about $15 and up, the spinning light up toys are around $20. The ever popular Mickey Mouse T-shirts start at around $20 and up.
You will want to take your time and browse the merchandise before buying to try to avoid all those impulse purchases. The one good thing is that prices are the same across property, so you do not have to worry about finding the same item cheaper somewhere else.
There are ways to save some money on souvenirs. There are some discounts if you are a Disney Rewards Visa card holder, or if you book your magical vacation package through your AAA office, they offer a discount card at certain shops, restaurants, and experiences. (Discounts vary, see your AAA office for details.)
Start saving for all the great Disney Merchandise just waiting for you at Walt Disney World!
