Much of this information I received right from the manager of merchandising while at the Disney race expo.
1.The pre-orders were done during the time of race registration. They were called "blind orders", because you had to order and pay for them without even seeing what they looked like until expo day. My sister and I did a "blind order" for the Marathon jacket this year.
2.This year (2015) was the first time that a pre-order has been an option ( I was unsure of this fact but this info came right from the manager). There was not a pre-order for Princess Half Marathon last year (2014). Some people were speculating that the White Jacket was the "pre-order" jacket, but it was not. This white tech jacket was bought at the expo.
3.If you pre-ordered (or blind ordered) a jacket for an upcoming Disney race you will pick this up in the same building where you will go for packet pick -up ( race bib), not at the expo building.
4.Note: The pre-order jackets will not be available for purchase at the expo. The expo will have a variety of other jackets, but not the pre-order ones.
5.If you are not pleased with your pre-ordered jacket ( or other pre-order items), you can return it. After seeing the design of the marathon jacket this year, I decided that I didn't really care for it. It wasn't a problem for me to return it. Just make sure that you have your receipt ( this will be on your registration form). Returns are made at the same place you picked it up.
6. If you are REALLY loving the pre-ordered jacket and you wished that you would have pre-ordered one too there may possibly be a chance you could get your hands on one. We were told that all the left over jackets ( or returned ones) are taken to the merchandise tent at the finish line.
Have you ever "blind ordered" anything?
