Does your wholesale site needs price discounts on multiple packs? For example, you have a product with 5 units in a box, then you want to offer 10% discount for orders buying more than 5 of this product, offer 15% for orders buying more than 10 of this product, with this plugin, the above scenario is totally possible, and eve the discount amount is configurable, namely the 10%, 15%. The plugin reads the units in box attribute of each product, and test against the current QTY in the cart, if the current QTY is higher than units in box, then the preconfigured discounts will be applied. All the conditions of the original virtuemart tax systems are still valid for this plugin, so it can filter by categories, countries, states, shopper groups etc This plugin is much more easier than creating product price ranges for each product. How to install 1.Install the zip file like any other joomla plugin 2. Extensions->Plugins->search for 'wholesaletax'->Enable the plugin 3.Components->Virtuemart->Products->Taxes & Calculation Rules->New->Select params specially for this plugin only, which is a little different from +,-,+%,-% operators.
