A Lightning Deal is a promotion in which a limited number of discounts are offered on an item for a short time.
All Lightning Deals appear on the "Today's Deals" page. To view this page, click the Today's Deals link above the search bar on any Amazon.co.uk page. These deals are available on Amazon.co.uk until either the time for that promotion expires or all the available promotional discounts are claimed. You can claim a particular deal once only.
When a Lightning Deal is available, here's what you'll see:
Note: When all the promotional discounts for a Lightning Deal are held by other customers, you'll see a Join Waitlist button and the status bar will show that 100% if the promotional discounts are currently being held in other customers' baskets or have already been used to purchase the deal.
