Free Checkout (OpenCart Addon)

Supported OpenCart Versions:
v1.2.6, v1.2.7, v1.2.8, v1.2.9, v1.3.0, v1.3.1, v1.3.2, v1.3.3, v1.3.4, v1.4.0, v1.4.4, v1.4.6, v1.4.7, v1.4.8

What does it do:
This contrib offers a "Free Checkout" option for customers when the grand total (after shipping and taxes) is calculated. This is useful if you offer free products like downloads on your store. Without this mod, there is no way to checkout because all payment mods expect you to have a positive amount.


Main features:

• Only displays when the grand total is 0.00.
• Checks all order totals and shipping dynamically before display to ensure validity even with custom future order total modules

How to install it:
1) Unzip and upload the contents to the root directory of your OpenCart installation, preserving directory structure
2) From the admin menu, go to 'Admin->Users->User Groups'. Edit the Top Administrator.
3) Find and check the new entries for both modify and access.
4) From the admin menu, go to 'Extensions->Payment'.
5) Install the module, and click edit to configure.

STEP 6 IS NOT NECESSARY IF USING v1.3.0.
IT IS NECESSARY FOR EARLIER AND LATER VERSIONS.
