I rented my wedding flowers through SBB and it was one of the best decisions I made in planning! No issues with waiting for them to open up, or needing to store them in the fridge, and if I needed to set my bouquet down for photos, I wasn't worried about a stem breaking. Absolutely NO ONE could tell they were fake, including our photographers.
Sending them back was super easy as well, though I do recommend asking a family member/your DOC to be in charge of collecting them before the party gets too crazy. Also worth mentioning, there was an issue with my package being addressed to an incorrect street name, and Lauren picked up my call and fixed the issue within an hour, if not even faster. I can't recommend this company enough!
