Orders & Payments

Credit Cards

We accept Visa and MasterCard. For credit card processing, we must receive:

  1. The name on the card.
  2. The card number.
  3. The expiration date.
  4. The 3-digit security code on the back side of the card.

Mail-Order Payment Options & Methods

Prepayment is required with mail orders the first time you order from us. Payment must be in U.S. currency. Postal money orders, bank drafts and checks in U.S. dollars should be purchased and used. Canadian customers can pay in U.S. funds by writing “US$” before the dollar amount on a personal check; your bank may charge a handling fee. Foreign bank drafts MUST be written on a bank in the United States and MUST have the bank routing code information printed on the bottom of the draft.

Foreign Ordering

We are happy to send orders anywhere in the world where the United States Postal Service (USPS) will ship to. USPS no longer provides a surface mail service, so all orders must be shipped by air mail. The Shipping Chart reflects the cost of air mail postage.

Invoice Payments

To pay merchandise invoices (invoice number starting with “Mx”) or periodical invoices (invoice number starting with “Px”), click here and enter your information in the right column under the heading “Pay an invoice.” You may pay an invoice with or without items in your shopping cart.

Damage & Replacement

As you wish, we will replace or refund your money for any items damaged in transit to you.

Quantity Prices

The discounts for ordering multiple copies of an item are found on the item’s detail page. Click on the image of the item or the words “More Info” to see this page.


You may return any item you have purchased from us and not used for any reason. We will refund to you what you paid for the item, but not the original cost of shipping the item to you.
