Interflora

It's not usually we can say this about a merchant, but if you want to know more about Interflora then check them out on Wikipedia! They're that big and they've been around that long (first started in 1920!)

Basically they are a florist service with delivery throughout the United Kingdom and worldwide. They have themed floral displays and presents suitable for birthdays, anniversaries, weddings, birth, and housewarming. Apart from flowers they offer hampers and present sets that can include wine, chocolates, gourmet delicacies and fresh fruit.

As their well-known marketing campaign said ... whatever it is, "say it with flowers".
