My Dh just sent me some this week, that he had ordered online. Poor guy, he was trying to be thoughtful on our 25th anniversary.
The roses arrived at 5pm, in a box. A vase was included, even though he specified no vase. The stems were bone dry--I have no idea how long those poor flowers had sat in that box, but they had NO water. A couple had broken stems, a few had brown petals, and there wasn't any preservative. To add insult to injury, they charged him $7.50 extra to deliver 25 roses versus 24.
He's currently trying to resolve this with the company, but I wouldn't recommend going this route.
