I didn't see a thread like this, so I thought I would copy out of the news comments for posterity.
What would be really helpful is to enable filtering out results not available online. The retailers tend to leave listings in their feeds long after the product is clearance and gone.
Target - "x Not Sold Online"
TRU = "Ship-To-Home" unchecked
This will reduce the lists to showing real, available discounts. Some people may want to see the YMMV in-store pricing, so filter option is better than eliminating the results.
