National Authors in Grocery Stores Program

Anyone with experience selling at, don’t laugh, grocery stores? Asking for a friend… seriously, there’s a group called National Authors in Grocery Stores Program that for $100 one time plus $25 per title, gives you access to Kroger and their owned grocery store labels. Your books get put into their system and you can set up book tables near checkout points. You get 60% they get 40%. My friend went from zero sales at local author fairs to 60 in a weekend and is growing her email list. She writes fantasy. It sounds kooky to me, but has anyone run across them? They claim 24 years in business. Please help my friend…
