Information regarding the right of withdrawal

Statutory right to withdraw

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).

We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.

We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.

We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.

You shall send back the goods or hand them over to Basement Seller 101, Cincinnati, Ohio, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

Exceptions to the right of withdrawal

The right of withdrawal does not apply to:

1. The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
2. The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.

Orders usually ship within 2 business days. Expected shipping times for "Standard" orders is 4 to 14 business days and for "Expedited" orders is 3 to 5 business days. We do accept international orders, although shipment times may vary, usually from 3 to 6 weeks.

If you have any questions about our shipment times and policies, if you need a book faster, or if you would like to check the status of your order, please e-mail us.

Please note that we ship all "Standard" items via US Postal Service Media Mail and all "Expedited" items via US Postal Service Priority Mail. Our international orders go via USPS First Class or Priority International Mail. If you would like us to ship an item via another carrier, please e-mail us and we will try to accommodate you.

We can overnight books domestically and send books expedited internationally for an additional charge.

The majority of our packages are shipped using Stamps.com NetStamps, a non-trackable method. Please note that all items ordered via the "Expedited" shipping method are automatically shipped with Delivery Confirmation. If you would like your item shipped with Delivery Confirmation, please e-mail us before making your purchase.

We ship orders every day, Monday through Friday, (excluding Postal Service holidays) usually by 12PM. If you need to cancel or make changes to an order, please do so as soon as possible -- many requests we get regarding orders are not fulfilled because we find, pack, and ship the book before the buyer contacts us. If you receive a confirmation e-mail from us, it means your order has been shipped and we can no longer make changes to it.

Please note that the majority of our orders ship out within 24 hours, many shipping out the same day they are ordered. Since we usually ship around 12PM, most orders received Friday after 10AM will not go out until Monday. In some cases, we will make a trip on Saturday to get more orders out.
