It was really painless. I bought something without paying attention and got the wrong model. Normally this means when returning the item I'm out the return shipping cost, but with the Kohls return I just walked into the store with only the item I was returning (unboxed, even) and they scanned a QR code from an email on my phone. There was zero cost and I didn't have to repack a box (though I did have to drive to a store).
