I think what it is, is the "free returns." It's free when defective or inaccurate description, where they will generate a UPS label.
Then, for any other reason, free dropoff.
I guess because we live in Phila metro, it's all the same to us....2 UPS stores < 1.5 miles, 1 UPS store < 3 miles, and Kohl's < 2 miles.....I was at first hesitant to use Kohl's, but then I learned it's no different than using a UPS label and perhaps easier in that we don't need to print anything out....it's always been about tracking for me....
