As Black Friday draws ever closer, I've been keeping a keen eye on the best Lego deals popping up around the internet. Reviewing Lego sets and writing about Lego forms part of my day job at That Brick Site, and I've been collecting Lego for a decade — so I'm putting my expertise to good use to help you save some money this Black Friday.
