I think one of the reasons for price increases on items on prime, is the amazon return policy. I used to sell on amazon, but 1 out of every 5 orders would be returned on my dime. Compared to my website where I get 1 out of maybe 800 returned and it’s always been something I overlooked before letting it out the door. Amazon customers just buy shit, and return it all willy nilly for no reason other then to waste time, materials, and other people’s money. I no longer sell on amazon because of that, their high percentage from each sale, as well as their photo policy. The products I sold needed the product pictured on another product,.. just having a picture of what I make by itself wth a white background,.. Hell I wouldn’t be able to tell you what it did or what it was for by that main picture.
With that said,... I use amazon daily buying all kinds of stuff for my business and for Christmas. However I try to never return anything unless it really is garbage or arrives broken.
