Thanks for posting this, I hadn't seen this before. I'm having a destination wedding and have only begun looking at bouquets. Looks like I might give this a try.
I'm guessing they would be delivered to you through 1800flowers. But I wonder if you could get them that day because you wouldn't want them the day before, they would die. Maybe you could pick them up at a local seller too??
Never done the bridal package...but I was once in 1800flowers arrangement of the month....ugh...that was a nightmare...i sent 3 arrangements back because the flowers were half dead on arrival...and then canceled because after i complained they still showed up wilted....poor DH thought he'd found the perfect gift...but it just ended up being a hassle....
As for Costco...they have wonderfully fresh flowers every time i'm in the store....
I would totally use Costco for my wedding flowers if I was getting married back home. Their flowers always look so nice and they even have wedding packages that include the brides and bridesmaids bouquets and all the boutinieres.
