When I have ordered jerseys from the Steelers Pro Shop online store, they’ve arrived in like two days with the free shipping. Maybe it’ll be the same if you buy from the Eagles shop.

But yeah you’re probably stuck to online buys. Fanatics.com, nfl.com, etc. Dicks Sporting Goods almost always ships items to arrive early as well.
