Because it's an 'add on' item?
Seriously? I added another cup to the item so the checkout button came up, went to click through and it said we'll save your add on item for later. NO, I want it now you twats, the whole reason I am here is to buy that that has not said its an add on item until very recently as only added it to basket a few days a go to serve as a reminded to fetch it today.
