ISUS is currently setting up an eCommerce site to purchase materials online, but having some trouble getting it to work properly. In the meantime, if you wish to order anything from the catalog, you can do so through the PayPal "Send Money" option, which does work with all major credit cards, and International orders.

The current catalog is HERE.

To use PayPal to purchase catalog items:

1. Calculate the total amount of the purchase.
2. Calculate the shipping.
3. Add them together and use PayPal to send that amount to:
4. MAKE SURE to put the items you want in the Comments section, or email a detailed list of items and any other instructions to the store email address and make sure you use the SAME email address you used in PayPal (or else we can't connect the two).

Shipping to the US/Canada is by media mail, and takes 1-2 weeks. For other mailing options, email the store with your requirements.

If you are within the USA or its territories served by the United States Postal Service, we can ship priority mail. Due to the weight of the books, "flat rate" is the best alternative. We can normally fit about 4 8.5x11 books in a flat rate box, and 6-7 of the smaller books. See catalog for sizes. If you wish to use Flat Rate Priority Mail, please use $10.00 for shipping (no per-item charge, as long as it all fits in the box). If you don't know, email the store and I'll see if it fits or not. If you would like to pay the regular priority mail price, it is about $5.00 per book on the average.

Domestic mail will be confirmed with a Delivery Confirmation number. International sales will have a US Customs number for tracking.

If you are a bookstore, reseller or have a large order, please email the store and we can arrange a discount.
