Florists in Singapore typically want a full 24 hours notice since they prepare the conditioning of the flowers during this time in order for the flowers to survive longer in a bouquet when delivered to the recipient. Some flower delivery services will charge an extra cost of the purchase amount if the notice is given less than 24 hours before delivery. To be compensated, the buyer must share the expense of workman hours and floral costs. Some florists are more accommodating, so make sure to read all of the terms of purchase before confirming your flower delivery.
