"BEWARE! I ordered two dozen long-stem rainbow roses with a vase for Valentines Day and instead got a dozen pink roses and a dozen orangish roses with NO vase. Last I checked, two colors does not make a rainbow.
I contacted their customer care department and was told: “In our desire to provide the freshest flowers available there may be instances where substitutions are necessary when fulfilling your order. If the product you are requesting is not available, we will substitute it with a similar stem or bouquet at the same or greater value of your order, to maintain the intended presentation of your order”.

First off, what I received was by no means "same or greater value." Second, my order was in no way close to what their ad clearly indicated. Last, according to their own statement above, they can substitute two dozen dandelions.

I would never order from this company again since you have no idea what they will substitute."
