Buc-ee First Timer Questions

I’m passing through San Antonio in a couple of months and a stop at Buc-ee is on my list of things to do.

Since there’s going to be a few late night legs to my cross-country drive, does anyone know if Buc-ee stocks the Mtn. Dew KickStart energy drinks? (my favorite)

And, if I’m going to visit just one in the San Antonio-Austin area, what are the recommendations on which one to go to?
