I have Amazon Prime and I do always check to be sure my item is marked "free returns" or sold by Amazon or fulfilled by Amazon. Just yesterday I returned an item that I was disappointed in the quality. I went through the return process in my Amazon account online where in your past Order list next to the item there is a "return or replace item" button. Click that then answer the questions about why you are returning. A QR Code will be emailed to you almost immediately along with the statement that your return request has been accepted. Print the QR Code. I have not yet seen the Kohl's option. I have the option of Whole Foods or the UPS Store. I always take it to my local UPS store and have never had a problem or been charged for return shipping. The UPS Store gives me a receipt evidencing drop-off and Usually there is no line to have to wait in.

I received my electronic refund within a few hours; apparently when the UPS store processed shipping the return.
