Theresa Pugh stopped at a store near Lord & Taylor after eating at the restaurant a few doors down. She picked herself up a supplemental Medicare plan from the Horizon Connect store.

"I just felt like I wasn't being sold a bill of goods." Call it the retailization of health insurance. Shopping center owners may not be courting them as they would Apple or trendy fashion brands, but health insurers are increasingly opening stores alongside far sexier retail tenants.
