Certainly not Dicks Sporting goods. They dont carry it.

Pool/billiards stores.
Amazon.
Ebay.
Google "weight lifting chalk."

Outdoor stores like EMS and the like have it for climbers.

Was all I could find at the last minute last year and I havent run out of it yet. It works well enough for now, I doubt that finding the "right" chalk wont add 5 feet to my WFD.

Blue, red, white...it's powdered chalk, gonna be a bit messy no matter what color it is.

btw, it's mostly calcium sulfate, so it still has dessicant properties to keep the hands dry And I can smear it all over my face and run around like Braveheart.

Got to make up for my lack of throwing talent with a bewildering display of pseudohistorical showmanship. hehehe

Really though, I was a bit pissed that Dick's didnt have chalk when they carry a decent amount of weights/equipment. So omw home I was passing by the lumber store and had a V-8 moment,"hey !they got chalk!"
My blue collar roots are showing.
