I wouldn't call this a supercenter.
Maybe a Wal-Mart seed.
It's tiny but mighty. They have packed a lot of merchandise into a small place, and you can find nearly everything you need. They do have supplies for school, food, bicycles and clothes. But in the world's tiniest place.
Well the Wal-Mart next to ASU is smaller, but this would be an easy 2nd.
But don't hesitate to come in to look for your items. I'll bet they have 8 out of 10.
Nice helpful staff.
Store is really clean.
Restroom open to the public.
No overnight parking.
