I have put together a large collection of LEGO. I already had a large amount but decided to consolidate my collection and sell my unwanted items to pay for the ones needed to make up my collections. This was the start of something bigger! Little did I know that I would end up selling LEGO for my living! It can be hard work, sorting and cleaning and then constructing sets accurately with pieces from the correct era. It's worth it though.
eBay. I trade on eBay as Moor_Bricks and regularly sell old and new LEGO. When I run out of LEGO you will be sure to know, as I will call myself No_Moor_Bricks.
