To BK, re how a title can be shipped that has nothing to do with the title ordered:
Many times, the titles have nothing to do with how the orders are filled. Instead, an order number is used by the warehouse.
If a couple of numbers get transposed, it is easy for someone working in the warehouse to fill an order with the wrong item. Easy peasey.
Of course, it would help if the warehousemen were to cross-check the number with the title being ordered. And easy peasey. But that would require someone at the warehouse level taking the time to care about what they are doing. Sorry, I don't work at every store, nor at every warehouse. This wouldn't have happened on my shift.
I hope you get the title you originally ordered, without too much fuss. At least you're getting a freebie, which is a good thing... I hope.
