Rite Aid: 70

Pharmacy chain Rite Aid gets a 70 score on the Human Rights Campaign's Corporate Equality Index--the second-lowest among such stores. Only Walmart has a lower rating at 65, and Walgreens, by contrast, gets a perfect 100.

Rite Aid lost points in the index because it does not prohibit discrimination based on gender identity and/or expression nor does it engage in appropriate and respectful advertising, marketing or philanthropy.
