In my experience, food safety is the biggest priority…

“…especially when it comes to produce. Employees were required to sterilize cutting boards every four hours; they had to fill out a cleaning log each time the boards were washed. Some employees would try to get out of doing the dirty work, so it was my job to pop into the department throughout the day and check the log.” —Linda King, former store and department manager for a Connecticut chain

We’re very aware of the role that the senses play in marketing

“If you used to buy a six-pack of soda and drink six cans a week but now buy a 12-pack because that’s the current standard size, you’re probably going to start drinking 12 cans a week.

The ten-for-$10 promotion is one of the most effective

“When a store does it, volume takes off, even if the promotion raises the price of something. We’ll take an 89-cent can of tuna and mark it “ten for $10,” and instead of buying six cans for 89 cents, people will buy ten for $10.” —Jeff Weidauer

There’s a lot that grocery store employees will do for you if you just ask

“The butcher will tenderize meat for you, the baker will slice a loaf of bread, and the florist will usually give you free greenery to go with your loose flowers. At some stores owned by Kroger, the seafood department worker will even coat your fish in flour or Cajun seasoning and fry it up for free. I couldn’t believe it the first time they did that for me.” —Teri Gault

It’s almost always cheaper to buy a large cut and have us trim it for you

“We can cut a chuck roast into stew cubes, a whole boneless strip loin into New York strip steaks, or a flank steak into stir-fry strips. We’ve had people buy one big roast and have us remove the bone for soup, run half of it through the grinder for hamburgers, and cut the rest into a pot roast. That can save you about 30 percent compared with buying everything cut.” —Bradley McHugh
