Every Kit includes 1Mb of Secure Server Space.

Secure Server Plan 1 is an option that can be added to your kit for $15 per month. This plan includes credit for up to 30 secure transactions each month (normally $0.75 each, or $22.50 per month without a secure server plan). This covers the costs for receiving, compiling, storing, and delivering secure transaction information that is submitted through your secure pages.
