Return Policy

30-Day Return Period

There is a 30-Day Return Period for non-workbook printed matter. Workbooks designed for writing on are non-returnable. Except as provided above, all printed materials may be returned to POIS up to 30 days from the date on the invoice for a credit or a refund of the purchase price paid, less shipping and handling and any applicable restocking fees and taxes if already paid. Any product returned to POIS without prior authorization from POIS will be considered an unauthorized return, and the customer will not receive credit for the product and POIS will not ship the product back to you. Refunds or exchanges for defective merchandise can be made within 30 days of receipt of the merchandise.

Our policy lasts 30 days. If 30 days have gone by since your purchase, unfortunately we can’t offer you a refund or exchange.

To be eligible for a return, your item must be unused and in the same condition that you received it. It must also be in the original packaging.

To complete your return, we require a receipt or proof of purchase.

There are certain situations where only partial refunds are granted: (if applicable)

  1. Book with obvious signs of use.
  2. Any item not in its original condition, is damaged or missing parts for reasons not due to our error.

Refunds (if applicable)

Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund. If you are approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within a certain amount of days.

Late or missing refunds (if applicable)

If you haven’t received a refund yet, first check your bank account again. Then contact your credit card company, it may take some time before your refund is officially posted. Next contact your bank. There is often some processing time before a refund is posted. If you’ve done all of this and you still have not received your refund yet, please contact us at returns@pois.com.
