Quick Updates plugin [support]

[craftzombie]

or display WHOLESALE_PRICE without and with TAX.

You can display the wholesale price without tax by going to:

admin\includes\extra_configures\quick_updates.php

find:

// change to 'true' to enable wholesale price updates
define('QUICKUPDATES_MODIFY_WHOLESALE_PRICE', 'false');

and change false to true

But as far as displaying those prices with tax... I can't help you there!
