Products prices and promotional prices

Hello, I'm synchronizing products from http://www.puppis.com.ar.

I'm having issues for the products with discount prices. For example:

http://www.puppis.com.ar/seresto-collar-antigarrapatas-perros-hasta-8kg/p

Has a price of 732 and a promotional price of 549.

On the api response the promotional price is not showing.
