Significant delay of arrival after the given date of delivery (I ordered 2weeks to my due date so that's my fault) however if there is a date of arrival timeframe provided and it then exceeds that, or a change of the latest possible delivery date - I feel notice should be offered rather than need for the customer to follow up. Urgent order was sent from China and packaging was badly damaged on arrival which meant it was unable to be gifted. Products themselves were great!
