Sounds like a very high number.
Ill say. One thing kohls is doing is returning amazons items if people want to. Just drop them off there. I cant imagine more the 5-10 percent are returned.
You can’t generalize of course, but I order a lot of stuff online and my return rate is nowhere near 30 percent.
I’ve also had retailers who didn’t want returns- they have allowed me to keep the item and encouraged me to donate it while still giving me a credit. Usually that has happened with low-priced items, not defective but not the right color, not fitting as expected, and so forth.
