Click Add To Cart and enter your invoice amount as quantities.  I.e., $500 is a quantity of 500.  No need to add cents!

This is a new checkout system as of August 1, 2017, and requires a new account be created (sorry!).  Your former Caledonia.Net account is not linked to this.

You can pay via Paypal or scroll down to fill out the information for credit card payments.

Thank you.
