Nice! Here's my 10 seconds experience: in the search results page I got the sentence "Showing 125 cards worth between $10 and $200 discounted from 0% to 50% for ITunes." But the actual results have discounts between 8 and 10. In fact I clicked on "from 0% to 50%" and tried the range 45-50 but got no results; incidentally this distracted me from realising I could have clicked the column header and sorted in the first place. Perhaps the the sortable headers functionality should be more prominent by design. Great idea anyway!
