The media, shoppers and general public await the curtain draw and big reveal…

The curtains are drawn to reveal a single bag of blood hanging on a golden stand.

The message is simple; There is nothing more valuable than a bag of blood, a gift that we can all afford to give, and one that could save a life.

This reveal coincides with World Blood Donor day.

The NHS blood donation team are introduced and viewers are invited to schedule appointments to give blood.
