I have been a retail store manager for over 20 years, and the most difficult situation's that can sometimes arise are with returns.
I recently was by looking for a personal desktop type evaporative air conditioning unit for my office space. I went through and read all the reviews offered of the top 10. Figure I would pick from 1-3 depending on price, and it was off season so some I might find on sale.
I found that most were on sale as close-out models. Except for #1@ $55. More money than I wanted to spend on my desktop.
Anyway I started with #2 model out of top 10 and ended going through 4. Before I found just one that actually would not leak.
Amazon Has no problem just taking them back one at a time as I would try them out no problem with customer service issues. All you had to do was give them a short explanation to why you return them. And then you could take them to your local Kohl's store in my area, Without even happen to put it in a box make a label or absolutely anything. Just take it to Kohl's they label it scan it everything send it back worry free. As soon Kohl's scans the product for return you get a refund back onto your card, Or how you purchased the merchandise.
Amazon I believe has the most outstanding customer service relations in returns policy better than even Walmart has you don't have to stand in line all you have to have is hit the button and take it to Kohl's or your local UPS store and you get a refund as soon as they scan it. I would definitely recommend Amazon as a place to shop online.
