I decided to purchase a Rails shirt that was sold out elsewhere--no tax and all at SS so I thought I would give it a try. I always check for final sale prompts in the checkout, because I like to be able to return if there is an anomaly. At the time of the purchase, this was not a final sale, but the shipping ticket said final sale, and no customer service was available during regular hours.
I will say that the shirt was new, although cut rather unusually large for Rails, but now I have a huge shirt that cannot be returned, and I guess I will try to shrink it.
Update: I received an email from customer service that they would honor a return this one time. Awesome. I suggest copying the page when you submit, so there evidence of whether the item is final sale.
