If you drive from the LGB airport to the GC on Katella (Willow in Long Beach), there is a Target in the city of Cypress. It is at the corner of Katella and Knott which is about half way to the GC. There are a few grocery stores along the same route as well as a Costco. The grocery store I would recommend is the Albertson's at the corner of Katella and Brookhurst.
