Has anyone tried Grandmas Brownies

I was tasked on finding fire edibles for a friend of mine who's looking to stock, been thinking about testing out some of these 300mg Grandma’s brownies. They look like they’d move well as a budget edible with a decent milligram count, but I haven’t heard much about them from other shop owners.

Anyone here stocked them before? Curious about the shelf stability, packaging quality, and whether customers actually return for them, or if it’s just an impulse buy.
