A good destination for Sun Devil gear! There's an excellent selection of t-shirts, golf shirts, hoodies, caps, baby stuff, car accessories, etc. The prices are OK but the quality of the wares seems to be better than most places.
Students come here for the textbooks too (is that still even a thing? Don't you download books now?), which are located in the basement area. I feel like Campus Corner was around when I attended ASU in the mid-late 90's. There's another legacy competitor right next door and brand new "ultra-modern" school store has opened across the street. So this corner has quickly become the spot to shop for ASU wares.
Grab some food across the street or walk a couple blocks to Chuckbox for some nostalgia, great open flame burgers and an ice cold beer.
