Question: My child is interested in making some of the models featured in The Unofficial LEGO Builder’s Guide but we don’t have all the pieces. What’s the best way to find/buy LEGO pieces?
Answer: In speaking with parents of kids involved in LEGO building, this is perhaps the one question that comes up most often. The answer, unfortunately, isn’t cut and dry but before I tackle that let me back up just a bit.
One important thing to point out about the book is that every attempt was made to include instructions and examples that could actually be built by kids or adults with limited sized LEGO collections. It’s simply not realistic to believe that everyone who loves LEGO also has 100,000 pieces sitting in their basement. With that in mind I attempted to design the models in the book to be fun and instructive but at the same time be constructed with fairly common pieces or at least pieces that are reasonably easy to obtain.
Which brings us back to the question, “what’s the best way to buy LEGO pieces?”
Of course the first and simplest answer I usually give people is to visit their local toy store or to check out LEGO’s own Shop At Home service. But what sort of products are you looking for? Again, not a straightforward answer, though not hugely complicated either. In some cases you’ll want to try and find nothing more than the large assorted buckets and tubs that LEGO typically has for sale at any given time. The contents of these assortments changes every year or two but the idea is always the same: lots of basic bricks for not a lot of money. Here’s a pic of two recent offerings along this line.

Buying those types of LEGO products will give you lots of basic bricks, but what about some of the more interesting specialized pieces? For that you may wish to turn to some of the themed LEGO sets. That could include Harry Potter sets, Star Wars sets, or even LEGO’s own Designer sets. All of these offer fewer pieces for more money but also offer a wider variety of elements that you may find useful for your own models.
Another way to go, if you want to buy specific LEGO pieces, is a site called Bricklink. Here you’ll find hundreds of virtual ’stores’ where you can pick out only the parts you need in the colors you want. You may find that individually these parts seem a bit more expensive. But what if, for example, you wanted 10 red 1x4 arches? It’s entirely possible there’s no single LEGO set on the shelves today that contains that many of that piece in that color. However, on Bricklink it’s quite likely you’ll find someone who can sell you just those pieces.
Finally, there’s the ever popular eBay, though like anything else on that site you must adopt a ‘buyer beware’ attitude when bidding on LEGO items.
The point of buying LEGO is that it’s not always cheap and sometimes takes a bit of creativity to find what you want. But in the end the reward is more than worth it. LEGO bricks today still connect to and work well with bricks made 10, 20 and even 30 years ago.
