As a long time resident and past student I can confirm that in all my experiences the Jayhawk Bookstore has exceeded expectations in customer service, product selection and competitive pricing.
Their staff is knowledgeable. JBS has the larges selection of Art supplies in the area. I love the artistic Jayhawks out front. Parking is not a problem; but they do confine it to customers. No park and leave; or go to class.
Their jingle is one that sticks in you mind.. that's good.
