Utah mother upset with PacSun T-shirt display buys every last provocative shirt
Someone should tell this woman that using her bank account to impose a sort of quasi-censorship on the store will only cause that particular shirt to be restocked in greater quantities later on. After all, when the people who who manage the store's supply see how well that shirt is "selling," they'll probably just think it's really popular and order more. Not a very bright idea...
Stores have return policies to enhance customer satisfaction. Any store that allows returns of non-defective items does so because it values you as a long-term customer more than it values the profit from that one sale.
The store manager would be well within his rights to refuse the return and I hope he exercises that right.
