Augleo: If buy the chocolate hearts no packing. YOu can always buy the gift packs or organza bags from concourse if you want to make it look pretty. Alternatively, you can print a thank you card, then stick the chocolate (using double sided tape) to the card. You can print flower stalk with no flowers, then stick the chocolate hearts one it like a flower.
I have about 60 guests so if, I give each guests 2 hearts, I will need about 120. If 3 hearts, it will be 180 and progressively lor. I have bags available (must go and dig) so if you wan, I can pass you some also (provided I can find them!).
