Product::getPricesDrop do not includes prices drops in variations.

[Rodolfo Ortega]

Hello to all:

I am using this code

$products_with_discount = Product::getPricesDrop($this->context->language->id, $page, $page_size);

To get all products offers. But I find it does not return products offers in variations. 

I have a product with an offer on a variation in the size. It does shows the product, but it does not show the variation URL and the price.

Can anyone give a hint on how I can get the variations offers? There is another place where i can ask this question?

Happy holidays!

Thanks!
