Did it have your name on?
Sometimes sellers send the wrong item in error. Could it be from a seller you have ordered from and you are waiting for an item and they have sent the wrong thing?
If you are sure it was not intended for you, it could be a brushing scam which seems to have resurfaced or, if it is low cost item, could it be a return that a buyer has sent back and the seller is using a random UK address (yours) rather than paying for an item to be sent back overseas?
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
