How to eat well and save money

Three years ago, when I was in the United States for my postgraduate studies, I received an unexpected call from my grandparents one day. I knew then and there I needed to go shopping for their dietary supplements.

They are big fans of cod liver oil, odorless garlic capsules, grape seed extract capsule, Ginkgo Biloba and Caltrate.

Every time I flew home for a vacation, my grandparents would request me to fetch them their favorite dietary supplements. They believe such products are good for their health. Typical shopping bills would total up some 8,000 yuan ($1,151) a year.
