I'm also looking for a similar app. I've never used Flipp or Reebee, but I checked out their websites and they just seem to provide a much easier experience to browse various online flyers, price matching, clipping and saving items to a shopping list etc. I've scoured a little bit through the windows store, they seem to only have very poor apps thus far, like Shopsavvy, and Redlaser... I tried ShopSavvy and it seems to be fake, I couldn't get any results from it at all, and its experience made me wary to even try RedLaser.
