You can specify the delivery date. But do yourself a favor and give a few days notice. I have ordered on a Friday for A sunday delivery. No problem. So its pretty quick. You can also ask to have the florist do something a bit different as well. there is a comments section. For example, if you ordered a dozen roses, you can ask for..say..6 red and 6 white...if you wanted to personalize the flowers. One last thing. If you want flowers delivered on a holiday, ( womens day for example) do so way in advance. The closer you get, the more expensive they become.
