Diane Ratliff was on the hunt for some fresh fruits and vegetables. She pushed her small shopping cart to the back of the store and picked up a package of asparagus and some baby tomatoes. Then she dropped a small container of blueberries in the cart. 

"These are $1 a pack!" she said. "This would be way more expensive at the grocery store." On this recent day, the Galena resident wasn't shopping at a typical market. Located inside a produce terminal, Ratliff was at Sanfillipo's Cash and Carry, which is part of the larger Sanfillipo Produce.
