One of my merchants (4checks) publishes a lot of duplicate checks that datafeedr doesn't recognize as duplicate. They have two versions of checks with the exact name, description, (everything really) except price. After further research I noticed the difference between them is one is a single check $19.95 and one is a duplicate check $23.95.
I guess datafeedr keys only on the product ID which is why it's not seeing it as a duplicate. Is there any way I can filter these out of the mix without having to go into hundreds of categories and block each check separately?
