A Hawaii snack maker has rolled out a li hing powder candy line at Walmart, with prices cut just as families stock up for the school year.

• Enjoy Snacks now sells seven li hing flavored items, including sour gummies, 3D gummies and dried mango.
• The whole line is on rollback pricing at Hawaii Walmart stores, timed to back-to-school shopping.
• Li hing is a salted plum flavor brought to Hawaii by Chinese plantation workers in the early 1900s, and it turns up in everything from drinks to desserts.
• A monthly giveaway for a snack basket runs through the end of August, with entries resetting each month.

Outlook: Expect the li hing line to lean on cheap back-to-school pricing to win shelf space through the fall.
