If you're visiting the site from within the UK, you'll notice a new Argos box in the right hand menu.
Brickset has been an Argos affiliate for some time but it's only just now that I thought I'd exploit their product feed and see if I could do something useful with it.
So, the box on the right currently shows how many LEGO products they sell and how many are reduced. They have some good reductions from time to time so keep an eye on that figure then click through to see everything that's reduced, something that normally takes a few clicks on the Argos site. Better still, it shows the best bargains at the top of the page, which is not possible on their site.
If this proves useful I'll look at ways to determine when new products are added. Remember, everything you buy -- LEGO or not -- or even just reserve at Argos resuts in a small kick-back to Brickset.
