'Hello - Just writing to let you know my sister thought the arrangement beautiful and described the flowers as indicated on your website - she really sounded impressed with how they looked. Thank you also for getting it to her today - her birthday. Only issue - I chose it not only because of the flowers in the arrangement but because it had a Happy Birthday balloon as well - to distinguish the reason for the flowers. But her order did not have the birthday balloon. Virginia Tennyson'
'Very pleased with your service. The flowers were beautiful, very pleased with the arrangement.'
