Configuring wholesaler group with specific tax

[SublimeVizion]

Hi all. I've set up a "wholesale" customer group with its own .5% sales tax. I've noticed that sometimes paypal will not include the tax. It's funny but it's usually when there are 3 items in the shopping cart. When i have 2 or 4 items paypal will show and include the tax. It only happens with my customers under the wholesale group, paypal works fine with the regular customers tax. This is the code i used and put the Tax.php file into override/classes/tax...

 

public static function getProductTaxRate($id_product, $id_address = null, Context $context = null)

{

  if ($context == null)

    $context = Context::getContext();

 

$address = Address::initialize($id_address);

$groups = Customer::getGroupsStatic((int)($address->id_customer));

$taxratenew = null;

foreach ($groups as $g) {

if ($g == 5) {           

$taxratenew = .5;

  if (!$taxratenew) {

  $id_tax_rules = (int)Product::getIdTaxRulesGroupByIdProduct($id_product, $context);

  $tax_manager = TaxManagerFactory::getManager($address, $id_tax_rules);

  $tax_calculator = $tax_manager->getTaxCalculator();

  $taxratenew = $tax_calculator->getTotalRate();

}

  return $taxratenew;

}

 

 

Anybody know why paypal sometimes excludes the tax for wholesalers??? Thanks in advance.
