Brickficiency

I've started putting together the May order for the Falcon. My hope is to get enough parts to complete steps 54-60, which will mean that I have to pick-up 528 LEGO (roughly 1/10th of the set).

On orders this large, it is nearly impossible for a human to figure out a the cheapest way to order that parts. I use Bricklink for my orders (it's like a LEGO only eBay), but there are literally thousands of sellers with millions of bricks there, sorting through that to find a cost effective way to order is painful and slow.

Bricklink has some tools to help, for example you can enter a wantlist and then search for sellers that have all the bricks you want. The problem here is that they cab be huge difference in what various sellers want for a particular part. For example, my May order, there are 2 sellers that have all the parts I want, the total price for the lot are listed as $480 for one and $420 for the other.

Reading through both sellers offerings, I see cases where Seller A wants $3 for a brick while Seller B wants $0.30, and the reverse where Seller B wants way more of a different brick than Seller A. If I could only get the cheap bricks from each, then I could save a ton of money.

But how to to this? There are two sellers that have everything, but there are thousands that have a partial list. I have the go through them all, figure out what they have, and compare the prices.

Enter Brickficiency. Download the app, run it, give it your Bricklink account info (or a LDD file from Lego Digital Designer) and let it go.

It will scourer Bricklink for you, searching all the Sellers for your parts. You can control how many Sellers it will spread the order over trying to find the cheapest solution. It does default to stop as soon as it finds a solution (usually all the bricks in 1 store) but you can set it to continue past that point. Note: this can take a long time: if the status bar is any indication, it's going to take a few hours to find all the 3 Seller combinations for my order. Easily worth it if it saves a few hundred bucks!
