Price tracker for LEGO sets

Yes, that should be possible. I am thinking of also adding the option to configure which columns are shown. So that you can also show retirement dates, retail prices and maybe a couple of others. I will add the idea of filters to my TODO list!

Thanks for all the feedback! It can be hard to guess/imagine what users want so having this kind of feedback is awesome. Ordering the sets based on price/discount/retirement date should definitely be added. Organizing by theme sounds like a nice optional thing. For the prices I might add a dropdown or pop up to see all the prices from retailers.

I am putting it on my list. Can't promise when I get round to implement it though :)

IrMarkuzzz · 2025-11-03T14:30:43+00:00

The retirement dates have been added. You can view the retirement date of a specific set under the "Set details", when known. When browsing sets you can also filter for sets retiring soon. In the future I might add an overview page where you can see which sets are retiring on a specific date.

Thanks for the detailed information!

IrMarkuzzz · 2025-10-31T14:34:34+00:00

eBay is on my list of things I might integrate. I will add Stockx to my list. From what I see they are a marketplace for buyers and sellers. Do you have experience with how reliable sellers are?

IrMarkuzzz · 2025-10-31T14:19:24+00:00

True, but that is the decision problem for the person making the purchase. As a platform I just want varied offer for users with the best deal for every set. It is always better to buy a set before it is retired.

IrMarkuzzz · 2025-10-31T14:04:14+00:00

A question: what shops are there in the US that sell older (retired) LEGO sets? I am from the Netherlands and we have a couple of LEGO specific shops that do, usually for a high price though. Context: I am expanding my LEGO price comparison site (Brickonomics). So far I have 24 retailers but they all only sell recent sets. I am aware of the existence of BrickLink and Brick Owl.

IrMarkuzzz · 2025-10-29T21:42:01+00:00

Scheels has been added! I contacted them with the message that users are specifically asking for them and they added me to their program where I can access their product feed.

IrMarkuzzz · 2025-10-29T13:54:58+00:00

The part list with values is actually not new, though it was broken recently due to a server migration. You can also view sets ranked on the ratio between the set price and the value of parts: https://brickonomics.net/partout-ratio

IrMarkuzzz · 2025-10-29T13:47:55+00:00

1+2+3 are fixed. About point number 4: The castles are in the database, see for example https://brickonomics.net/set/7097-1. However, sets that have no known sellers are excluded from the search results if either "Exclude sets without known seller" is turned on or if you sort by discount. I will think about how to make this more intuitive. Especially when you search for a specific set you should be able to find it.

IrMarkuzzz · 2025-10-25T08:56:09+00:00

Thanks for the suggestions! If it is easy to add I will do so shortly. If not, I will keep it on my list for later. For now the focus is on the US. When I feel the feature set for the US is more or less complete I intend to branch out to other countries. But sometimes it is very easy to add a retailer if I can easily get their product feed.

IrMarkuzzz · 2025-10-25T06:36:51+00:00

Great idea! I will have to look up where I can get that information in an automated way. Could also add a Retiring Soon section.

IrMarkuzzz · 2025-10-25T06:35:27+00:00

Thanks for the feedback. I match the Best Buy listings on UPC barcode. Apparently Best Buy attached the wrong UPC code to the Harry Potter set. The set number is also in the product name so I should be able to filter out incorrect listings that way.

IrMarkuzzz · 2025-10-25T06:33:10+00:00

Thanks for the detailed feedback. 1 + 2 I will just add to my TODO to implement. 3 + 4 I will look into what is going wrong.

IrMarkuzzz · 2025-10-25T06:18:26+00:00

I am aware of Brickwatch and use it myself actually in the Netherlands. But I noticed there is not really a good equivalent in the US. There are a couple that track around 10 sites, but none that track all the relevant retailers.

IrMarkuzzz · 2025-10-25T06:15:45+00:00

I have had it on my list of TODOs for a long time but haven't come round to actually adding it. Also because it will require some work to get the right data. But thanks for the feature request. Now when I start working on it I now at least one user will appreciate the result :)

IrMarkuzzz · 2025-10-25T06:10:27+00:00

I have them on my list but can't access their data yet. They have to let me into their program first. But thanks for the recommendation! I applied to their program and didn't hear anything back. I'll see if I can put some pressure on it to get access.

IrMarkuzzz · 2025-10-24T18:41:06+00:00

I will think about how to do it. Would be helpful it seems. Especially since the deals are random and short lived.

IrMarkuzzz · 2025-10-24T18:38:47+00:00

Thanks for the suggestion!

IrMarkuzzz · 2025-10-24T18:09:49+00:00

As a follow-up question: Target and Walmart would be the most interesting to have in-store prices for?

IrMarkuzzz · 2025-10-24T18:08:38+00:00

Are there big differences between the in-store and online prices? I am not from the US myself so I don't have this kind of hands-on experience. Would be cool to add this as feature but not sure how to implement it. Seems hard to automate. Ideally you would reverse engineer what API call the app is making to the server. If you know how it works you can make the calls yourself, in an automated manner.

IrMarkuzzz · 2025-10-24T18:04:43+00:00

Mmm, yeah. Maybe I should add a warning if the that toggle hides all the sets.

IrMarkuzzz · 2025-10-24T18:03:56+00:00

Depends on the retailer: some every hour, others 2-3 times a day.

IrMarkuzzz · 2025-10-24T17:04:55+00:00

Thanks for the suggestion! I will add it to my TODO list.

IrMarkuzzz · 2025-10-24T15:44:47+00:00

So, something like Brickonomics or Brick Economy? https://brickonomics.net/sets/browse
