Working readme for module: Group Pricing Per Item -- in ZC 1.5.4

The following works in 1.5.4. Please make backups of database and website before doing any of this!!!!!!!!!!!!

1--> Upload contents of file"group_pricing.sql" via Admin Panel -> Tools -> Install SQL Patches

2--> rename folder /includes/templates/ "YOUR_TEMPLATE" to "whatever template you are using"
3--> rename folder YOUR_ADMIN to "whatever your admin folder is called"

4--> Optional, rename discount groups to what you like:
4,1--> /includes/languages/english/extra_definitions in file "group_price_per_item.php"
4,2--> /YOURADMINFOLDER/includes/extra_datafiles in file "group_price_per_item.php"

Change the "Group A" .. "Group D" variables to desired names:
define('GROUP_PRICE_PER_ITEM1', 'Group A');
define('GROUP_PRICE_PER_ITEM2', 'Group B');
define('GROUP_PRICE_PER_ITEM3', 'Group C');
define('GROUP_PRICE_PER_ITEM4', 'Group D');

5--> upload all the files and folders via FTP to your website. Have them overwrite existing files.
6--> Create discount groups. Go to: Admin Panel -> Customers -> Group Pricing.
Use the exact same names as you created in step 4,2

7--> assign the desired customers to the discount groups
