Although the dust after Black Friday has settled and it is already Saturday, Amazon continues to roll out new lightning deals. And you can conveniently track them on this page. All deal stats are also stored in the database so that when it is over I can publish some interesting statistics about how much time it took for each deal to run out etc.
… Enjoy! You can also track deals at Offical Amazon Deals page. Scroll down to see all currently active deals.
