My Add-On for MAP (minimum advertised price).

[DrByte]

The Plugin still displays etc but the quantity discounts displayed below the pricing show the lower price that is not supposed to be shown.

If you're using MAP pricing then you're probably requiring customers to add-to-cart to see the price, so therefore you don't want the discounts box to show at all;
therefore, you can cause it to no longer display by editing:
/includes/templates/YOUR_TEMPLATE_DIRECTORY/templates/tpl_product_info_display.php
You could remove the entire following section of code, or you could just make the change in red:

<!--bof Quantity Discounts table -->
<?php
  if (false && $products_discount_type != 0) { ?>
<?php
/**
 * display the products quantity discount
 */
 require($template->get_template_dir('/tpl_modules_products_quantity_discounts.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_products_quantity_discounts.php'); ?>
<?php
  }
?>
<!--eof Quantity Discounts table -->
