To place and order for our calculators, go to the Calculator Category Index page and begin browsing through the calculators. When you find a calculator you would like to license, click the "Add to Cart" button located beneath the calculator. When you've added all of the desired calculators to your shopping cart, click the "Check Out" button located on the Shopping Cart page.
Unlike server-side calculators that force your user to click the back button each time they want to recalculate, our calculators can be recalculated without having to load another page.
