Ordered flowers for a friend for her birthday and delivery date said the date of her birthday. Thought this was fine but yes I didnt pay the higher price for guaranteed. Expected as a date was given that would be fine. NO! Royal Mail are useless and so despite bunches sending on time flowers were not delivered the next day buy day after. Not exactly fresh then and too late for friends birthday. I would be changing your delivery provider. Customer service just told me its 95% chance wont be delivered on the date and I didnt pay for guaranteed so tough, in other words!
