So, I downloaded the shopping toolbar from Mileageplus. I did this for the 1,000 miles they are offering.

Anyone have any experience with using mileageplus shopping and the chase ultimate rewards mall together to get more points from a spend?

For instance, can I be logged into UR mall, go to say Sears.com to shop for 5x bonus while at the same time going through mileageplus shopping to get the extra 2x bonus?
