Supermarket Convenience

I have a convenience problem with supermarkets near me. There are 4 legitimate options: Whole Foods, Stop and Shop, Shaw's, and Russo's. Each has pros and cons and each sells things that I buy regularly as a "loss leader". I get granola bars from Whole Foods because they're 33% cheaper there compared to any of the other options. I get produce (fruits and vegetables) at Russo's because it's noticeably fresher AND sells for a discount of about 10%. Then for everything else Stop and Shop and Shaw's have the standard "Weekly Special" offers so I can get everything else that I need for pretty good prices. And while it's nice that I can shop around based on quality and value, having all these options is terribly inconvenient.

I attended a meeting the other day where they defined Value as Quality * Convenience / Cost. I think this holds true for my supermarket situation... if I want to adjust my situation to make it more convenient, I need to sacrifice 1 or 2 of the extra trips and either pay a little bit more or accept options that aren't as good quality. Ho hum.
