I think she realizes that this is not the ideal return policy and she is trying to minimize the impact that such a harsh policy has on sales.
Once again, read the return policy,

What she did do is punish religious people who return brand new unused clothing while giving a full cash refund to others.
By the way, greed, pettiness, and revenge exist outside of fairy tales too.
