Where can I buy a Harry Potter wand?

I am going to Orlando tomorrow cause I need to pick up my brother from special needs camp.I'm taking him to the Lego Store in Downtown Disney. I was wondering if there is a store it doesn't need to be in Downtown Disney but in Orlando that I can go to to buy a wand. I know they sell them in Harry Potter World but I am not going to go there just to buy a wand plus I'm going there in 2 months with my school.
