I'm trying to develop a web page which will automatically display coupon/discount information for a specified category.

I downloaded the data feeds file. It seems that there's no coupon information there.

And then I tried GoldenCAN coupon integration tool. But the tool can only provide coupon/price drop information for all products. I can't filter it into a designate category.

Is there any way to achieve this automatically?

Very appreciate for any help,
