Amazon refund Method working 

find something you want to buy or something you like, this method might not work for some things but has been used and worked for my pc, airpods, kbd etc
when you have the thing you want add it to basket.
then buy something else which is cheap, maybe £1 item
you can carry on shopping for things or you can proceed to checkout.
when you are at checkout you have to MAKE SURE IT DOESNT SAY DELIVERY NEEDS ONE TIME PASSWORD OR SIGNATURE
if it says this then that means that you won’t be able to refund it
one way to get around this is remove one of the items and see if it changes.
when refunding make sure that you say that the expensive item didn’t come or one of the items was faulty and send a picture of the other item(s) you bought.
