Fulfillment Policy

Thank you for shopping the System Dynamics Society.  Following are the terms and conditions that constitute our fulfillment policy.

You can also view our shipping policy document.

 

Placing Orders

We accept orders through our online shop or by email. Our contact information is at the bottom of all webpages.  Acceptable methods of payment include credit card, PayPal, wire transfer, or a check made out in US dollars, drawn on a US bank, payable to the System Dynamics Society.

 

Sales Tax

For tax purposes, we are located in Massachusetts.  All purchases made for shipment to Massachusetts will automatically be charged sales tax.   Please contact the office with appropriate forms of verification if you are able to purchase items with tax-exempt status.

 

Shipping Timeframe

We contract with Fulfillment by Amazon to ship nearly all books. Generally, we ship games from our warehouse for domestic and international orders.  We prepare and mail the shipment within 1-2 business days of order placement and payment.  Orders are not shipped or delivered on weekends or holidays.

Within the United States, you have the option for two delivery speeds with details provided at checkout.  Internationally, the shipment time varies depending on distance and location.  It seems to range from 5-10 days, though it can be more or less. If you would like to arrange for expedited international delivery, please contact the office, we can determine additional fees that will allow for faster delivery.

We now offer the Billibonk series of books through print on demand. These books have a longer timeframe for printing and shipping through our partner IngramSpark. Generally, they can take up to 10 business days for US-based shipping addresses. For international shipping addresses, the shipments are not trackable and can take from 10 business days to about 1.5 months to deliver, depending on location.

Shipping Costs

Shipping costs are paid by the customer.  These are calculated automatically when you make your purchase and will be displayed at checkout.  They depend on the size & weight of the item and the delivery location.  If you would like to arrange for expedited international delivery, please contact the office, we can determine additional fees that will allow for faster delivery.

 

Duties/Customs Policy

All duties (customs) and taxes are paid by the recipient.

 

Returns, Refunds, or Cancellations

We will accept returns for a full refund within 90 days of delivery with no restocking fee.  Please contact the office to make a request.
