If you like dead flowers then this is the place to go.
My lovely family ordered flowers for me from M&S for Mothers Day. They arrived by courier this morning. I think they're lilies, but it's hard to tell. They were in a box with a plastic bag over the flowers. The stems were very dry and the leaves and flowers were dead. Some plant food was enclosed, but it would take more than plant food to revive these specimens.
I have contacted M&S, but as yet have not received a reply.
