Tipping the delivery team $5 to $20 per person on the day of the event is common. Tipping the florist for a wedding is not expected but is always appreciated, especially if they go above and beyond to make sure your flowers are perfect on your special day. You can also send the florist a thank you note or give them a positive online review to show your appreciation. A positive online review not only thanks them but also helps their business.
If you're ordering flowers for a special occasion delivery, consider tipping the delivery person $2 to $5 at checkout if there is an option for it.
