With the huge increase of items going missing on the way to you or on your doorstep or scam addresses where the house holder does not even know a item has been ordered and sent to your address .

we strongly advise that you confirm reciept of your item 

preferable by ebay feedback system but simple message will do,

failure to do this could well mean your address is added to the unsafe address list and could effect future purchases,
