Numerical Methods For Partial Differential and similar items

It is our goal to make every order correct. If we do something wrong (or stupid), we’ll try to make it right including but not limited to full refunds or return shipping paid by us.
Our office runs by the golden rule. With that in mind civil and diplomatic communication goes a long way towards a positive outcome.

On the other hand sometimes people change their minds about an order. Returns are an expensive part of our business, so we must charge a restocking fee to cover these costs.
For discretionary returns we can accept a return upon these conditions:

1. The item must be returned in the same condition that it was sent, within 14 days of this email.
2. Item must be shipped back at the buyers’ expense in new protective packaging (bubble mailer minimum). We highly recommend purchasing some form of tracking or insurance on the item as we cannot be responsible for lost or damaged mail.
3. Arbitrary returns require a $2 or 20% restocking fee, whichever is greater (which typically includes recovery of paypal fees).
4. Items returned in used condition when originally shipped as new condition, or damaged in any way, may incur additional discounts.
5. Refunds do not include any shipping costs.

Please let us know when you have sent the item.
