• The biggest selection doesn't always mean the best: curate the produce section so customers can create a plethora of different meals from just a few simple ingredients.
• New and exotic produce can be a big hit if done correctly: visible signage and samples can improve the staying power of newly introduced produce for weeks, adding them to your permanent selection.
• Last-in-last-out: make sure the produce always looks fresh and appetizing.  Don't be afraid to throw out old or aging stock if you have fresh stock to replace it with.

Last, put effort into displays. The American consumer shops with his eyes, and therefore Weinstein advises, “Your job is to weave them into a display that becomes so appealing and so compelling to shoppers that they feel they have no choice but to select your food.”

Velazquez de Leon suggests using displays that contain nutritional information or health benefits of the produce, and also providing example recipes of how to use the ingredients. She states, “An aesthetically pleasing display is the only way to sell any product,” and therefore a produce display should appear strong, merging the individual colors and shapes of fruits and vegetables into one appealing display for the shopper.
