Grids Anyone from san francisco ?

I'm in need of a huge favour. I'm looking for someone who lives in san francisco. I'm flying to the u.s on march 17th. Staying in union square 9sir francis drake hotel)for a few days. I want to pick up grids in k-mart or bb&b . I know a lot of the time these stores don't have the stock in. So i'm looking for someone who lives in this area to help me out by say putting them on layaway if possible or give me some names of places to pick up piggies items also. Please pm me .
