Kohl's have good selections, sometimes SPorts Authority, but Academy is your best bet for local shopping. Hit up different Academy stores, too, some have more of certain items than others.

If you want jerseys, I agree with the other posters, go with aliexpress. I just got some Texans jerseys from them and they look great.

Except I must mention this Dwight Howard jersey for sale on Amazon at only $29.99. Not eligible for free two-day Amazon Prime shipping but it's a nice jersey, I bought one for a friend's birthday back in August. DO IT
