Returns Policy
We are dedicated to quality products and responsive customer service. Your satisfaction is among our highest priorities. If any part of your order is not what you expected, or if a problem beyond normal wear and tear arises at any time with a product you purchased at Differential Geometry, kindly email contact -at- differential-geometry -dot- com to let us know. We are happy to work with you!
We offer a 30-day return policy on all products except gift cards, special-order items, and items marked “final sale”. If an item you purchased from Differential Geometry is less than perfect, you may return it in original condition for a refund (purchase price; shipping and sales tax as applicable) within 30 days of purchase. Email returns -at- diffgeom -dot- com to request a postage-paid return label. (Please note: Garments or jewelry cannot normally be accepted for a full refund if they have been worn or laundered. If there is a question or problem, however, do email so I can discuss and resolve whatever may be the issue.)
If a package you purchased from Differential Geometry appears to be damaged on arrival, please photograph the package before opening, then check whether the contents are damaged. If necessary, email me immediately at returns -at- diffgeom -dot- com. I will provide a postage-paid return label if necessary, and either replace the item at no cost to you or refund the original purchase price, and as applicable, sales tax and shipping.
