I have bought from Amazon a lot and have returned some items over the years.
Amazon has recently changed how they accept returns, at least here in Austin.
Once I was able to request pickup. Amazon still offers it but now they charge something like $7.50
I can return free but i have to put item in box that it arrived in and tape it. I have to tape the label to the box. I am responsible for printing out. label or writing it very clearly and neatly on. a piece of paper.
I had the option of having. label sent to me but it cost me $1 and the label was on regular white paper. I still would have had to tape it to the box.
I do not know when Amazon changed its return policies. I do not return very often but just before I went to Paris, I bought several items. I wanted to return one of them and that is when I discovered the change. I decided to keep the item rather than return. The item cost $20 and was not what I expected but I could live with it.
But I diid not return it because of Amazon's changed policies. It was too much trouble to return.
I think that there are customers who excessively return and Amazon has to reduce excessive returns.
I do not know what the "magic" number is but if Amazon believes you to be abusing their return policies, they flag you and then I can not remember what happens. There is a penalty if Amazon believes that you are returning excessively.
ADDED. and after preparing the retuned item, I still have to take it somewhere such as UPS or Fed EX. I can not remember which one. And remember that I do not drive.
