There is a WDW outlet (two, actually) near Disney. The closest one is on State Road 535 (I THINK -might be 536), called the Buena Vista Outlet, and it's not far from the Downtown Disney area. However, I've been there, and it's really not all that great. The selection is really lacking.
The much nicer, and newly remodeled outlet is at the Prime Outlet mall, on International Drive, near Universal. I believe you would take the Kirkman Road exit off I-4 east and I-Drive is right there. Even though I'm local, I'm bad with directions.
This is a nicer store though, much nicer! They just re-did this section of the mall last year, so everything is very modern and bright. The store has a good selection of stuff, mostly things Disney was trying to clear out, and there are some good deals there. Lots of older pins, some plush, t-shirts, hats, sweatshirts, watches, collectibles, Christmas ornaments, autograph books, coloring books, toys, etc.
