I think that the Spa items that are being used shouldn't count for the items total, as it happens with the items that are equipped by the childs.
ye thats why i stoped buying them at all... just waste of space
And they should be given for free or as punishment.
there's over 750 item slots available, you would just have to unlock more slots. it's fair that they count as 1 stash. otherwise we would have to do the same thing as items & use gold/crystals to unlock spa slots as well as item slots
