Returns and exchanges should be painless. You have 10 days from the day the shirt is received to contact us for a return label. Simply email us at firstname.lastname@example.org requesting your return and/or exchange and we will email you a return label. Print and slap it on the box and either drop the box off at nearest USPS location or leave it with your local USPS delivery (wo)man. All returns will need to be post-marked within 7 days of receipt of the return label -- any returns outside of this window will be given store credit unless you've a convincing reason for missing the cut-off date (we are, after all, human...and so know that sometimes things just happen).
Note: if you want to exchange the item, just email us with instructions as to what you want and we'll handle the rest. Any adjustments should flow through to your credit card within 7 days of receipt of the returned (or exchanged) product.
