The Oldest Shop
Persephone first started selling her candy creations after she caught Hades snitching from her stash on one of her visits. She figured that if the god of the underworld was stealing them she might be able to make a profit and opened a shop when she got back to the surface. It took a little while for the snack to catch on, but soon all the gods on Olympus were talking about Persephone's Superior Snack. Unfortunately, most of them didn't want to pay, so she made most of her profits from mortals. Since she had an in with Hades and appreciated the purchases, Persephone made sure all purchasers of her candy avoided Tartarus in the afterlife.
