Does anyone know if there is a return label that is prepaid that they just charge you a flat rate for if you ship things back? I'd like to order a dress in two different sizes and am thinking about ordering a few other things, but if I have to pay for shipping at the post office vs a flat rate label to return I'll just order the dresses. The nearest store is an hour away and I'm not sure I'll be there anytime soon, otherwise I'd just return to the store.
