From the Marketplace Health Desk at WHYY in Philadelphia, Gregory Warner reports:  If the supermarket industry had its way, we'd all probably only be allowed shop when we're totally starving and we'd have to leave our grocery lists in the car to encourage random purchases of stuff we don't really need. Even the most aware shoppers among us aren't much of a match for marketing geniuses who've designed stores for maximum temptation and maximum sales. But what if grocery stores used what they know about us and our buying habits for good instead of evil?
