I have placed a couple of orders from Google express and 2x I got a 20% (limited to $20). It was nice to know easy Wal-Mart return was available.
My Karaoke player, I ended up ordering 2. The first one from Wal-Mart's website for $64. But then Google express gave me a father's day discount so I ordered another one and this one was $51!! I returned that first one.
Next I got 20% off another karaoke component!
So far seems like a heck of a good app!
