Stocking up on Chometz

Most of us try to get rid of Chometz before Pesach, but some people have a different view of things. A couple of days before Pesach I was shopping in a large supermarket in a not very religious area. There was a Russian couple shopping who stuffed their cart with about 20 loaves of bread. I guess they had to stock up on it for Pesach for themselves and all their friends since none of the stores sell it then. Unless that was for their seder and they were planning on having lots of guests.
