All sales are final.
If you choose to pull the trigger on a piece, it's a commitment you're making forever. While APC usually offers a 14-day exchange period on full-price items, buying one of these means no returns. This even applies to online orders. In addition, you're limited to a quanity of one collaboration item per style in your cart.
Not that it matters if you're just looking to flip things. In which case, you are a BAD PERSON.
