This site FINALLY solved the age old problem of ordering flowers online: what you see is NOT what you get. The aggregate images from social media of what flower arrangements actually looked like when they arrived and compare that to the vendor photo. You get tons of data points on the arrangements that consistently delivered and the ones that will make you look horrible. There are so many images that you can be confident in ordering flowers online now.
They also show you the total cost (including delivery fees and other charges) of getting the flowers delivered. Oh, and also give you any coupons so you don't have to scour the web for discounts.
