I recently tried to purchase several movies at the same time from 3 different sellers. The first time I tried to pay, it refreshed the cart and showed there were still items left in the cart. So I clicked to pay again and it refreshed my cart again, still showing some items in my cart. I clicked pay a third time and it finally updated and cleared my cart. I assumed that it was checking out from the three sellers separately, but then I looked back at my purchase history and saw that I had ordered/paid for multiple copies of the movies. I was able to cancel the duplicates with one seller, but the other seller was unhelpful and refused to cancel the duplicates. The shipping cost to return the movies is almost as much as I paid for them in the first place.
