Anyone here buying LEGO on Whatnot?

My wife uses Whatnot constantly for her stuff and it got me wondering if anyone here is buying LEGO on it.

She actually bought me set #75393 on there a little while back. The box was damaged so it went for practically nothing, but I checked the minifigs and they're worth $60 alone. She paid like $20 bucks for the set. Made me want to look at the platform more seriously.

Before I sink real time into it, trying to figure out if the live auction format actually gets you sets below secondary market on the regular, or if the damaged-box thing was just a fluke. We have had some times when we got stuff that didn't work or wasn't what was described and was able to return it no problem. Curious about others experiences.

LEGO Sauron’s Helmet #11373 - Found at Kohls for retail

Saw three of these sets at a local kohls for retail price ($69.99). I have it scored at 74 out of 100. The Sauron mini fig has a pretty hefty price tag on it own… about $40.

Is anybody investing in this set… or should I wait it out?

What LEGO investing topics are actually useful? I'm working on some articles for the users of my portfolio tracker.

looking for advice on article topics for my portfolio tracker site (bricktracker.net).

quick context first: i posted here about the site 27 days ago and got dunked appropriately on the AI flavor of my writing. I've been working on fixing some of the bugs that were pointed out since then. dialing in resale values, current deal prices, upgrading the portfolio dashboard, etc.

now I'm thinking about adding some how-to's and what-to-watch-for articles for the users. Mostly because since I launched the site, I've noticed that LEGO investors have wildly different thoughts, strategies, and outcomes. that knowledge isn't really documented anywhere clean, and I'd like to put some guidelines and references out there.

Some topics I've been thinking about:

- How to read eBay sold listings vs BE market avg

- Site comparisons: BrickEconomy vs Brickset vs BrickLink vs. Brick Tracker, which one to trust and when

- Theme deep dives... Star Wars, Marvel, Speed Champions, Ninjago, etc.

- Sets the resale market is rejecting right now

- What tracking 100+ sets taught me about retirement timing

- Calendar watches: best months to buy retiring sets

which of these would you actually open? what am i missing? if you have a specific LEGO investing question thats been bugging you and never gotten answered properly, drop it. ill credit anyone whose topic becomes an article.

Mona Lisa Set (31213) hit a low on Amazon. I think it’s a buy and hold…Here's my thoughts why

It is currently on sales for $79.99. Which is 20% off its normal retail price. On eBay it currently isn’t selling for much. $70, but BrickEconomy’s projections having it at $116 one year post retirement and in the $140 range 5 year post retirement.

Currently it’s projecting with confidence that it will retire in December of this year. 18 month hold, your sitting on a 45% return.

Has anybody had any success holding the LEGO art sets long term? Any issues with resale?

Last week someone called my LEGO investment toolkit "AI slop." Fair. Here's how it actually works.

Posted bricktracker.net here last week. Got 2.3K views, a handful of useful comments, and one person who said "more AI slop." Fair enough — most "LEGO investing tools" are scraper sites with no real curation. Let me show what's actually under the hood, address the resale bug a few of you hit, and explain the parts people asked about.

On the "AI slop" critique:

Honest answer — the SITE looks polished because I care about UX. The DATA isn't AI. Here's where it actually comes from:

  • Set metadata (names, piece counts, themes, images): pulled live from the Rebrickable API
  • Retail prices: manually curated daily — I check Amazon, Walmart, Target, Best Buy, and LEGO.com myself and update the database
  • Resale prices: BrickEconomy averages, validated against eBay sold listings for the top retiring sets
  • Retirement dates: cross-referenced between Brickset, Brickfanatics, and LEGO's own announcements
  • Deal of the Day: I pick it manually each morning based on a scoring rubric (discount %, retirement proximity, historical appreciation, resale velocity). No AI is making the call.

Tool stack is Supabase + Netlify functions + vanilla HTML/JS. No ML, no scraping bots, no auto-generated content.

The slop critique probably came from how clean the layout is. Trade-off I made on purpose — I'd rather it look like a real product than a hobbyist spreadsheet. But I get why "polished + LEGO investing tool + free + new" pattern-matches to AI dropshipping sites. Hopefully this clears it up.

Bug a few of you flagged last week:

>

You were right. Some of the resale prices weren't loading when sets got added to My Collection — issue was on the lookup function side, not the data itself. Fixed this week. If you saw it last time, refresh the page and add the set again. Should populate correctly now.

If it doesn't, drop a comment with the set number and I'll dig in directly.

On "how does it work" — quick walkthrough:

A few of you asked how to actually use the site. Four pages worth checking:

  1. Homepage: search any set, see live retail + resale + map of nearby retailers with stock indicators (Best Buy is live, Target + Walmart in progress)
  2. Hot Deals: filtered list of every tracked set sorted by flip margin %. Featured "Deal of the Day" pin at the top.
  3. Retiring Soon: countdown timer to retirement for every set with a confirmed EOL date. This is the page most of you said you wanted.
  4. My Collection: add the sets you own, see real-time portfolio value, ROI per set, and total margin. Sign-in optional — works in browser local storage if you don't want an account.

Watchlists support price alerts (free, email-based). Daily cron checks every alert and emails when targets cross.

What I've added since last week's post:

  • Fixed the resale-on-collection bug above
  • Added a daily "Deal of the Day" feature that auto-pins the strongest current deal to the Hot Deals page
  • Reworked the Hot Deals sort logic — now defaults to flip margin percentage instead of dollar amount (better signal for ROI plays vs. just expensive sets with thin margins)
  • Added the Brick Trader marketplace stub page (coming this summer — P2P sales between users)

Still on the list (haven't built yet):

  • BrickLink price sync (manual is fine for now but doesn't scale to 1000+ sets)
  • Walmart + Target real-time stock APIs (Best Buy is live, the other two are next)
  • Minifig-only search and tracking
  • Pro tier with email alerts at custom thresholds (free version works, Pro is for power users)

Honest priorities — building solo, paying for the APIs and hosting out of pocket, so things ship at the pace I can actually maintain.

Discussion

A few things I'd genuinely like to hear back on:

  • For the bug fixers: did the collection page work for you this week, or still issues?
  • For the "haven't dug in yet" folks: anything specific that would make you actually use it daily? Email digest? Better mobile layout? Different sort options?
  • For the "AI slop" person (if you're still reading): what would change your mind? Always open to specific feedback.

Free, no signup required for the deal feed, no affiliate links pushed in your face. Comment with set numbers you want priced, I'll add them.

Built a free portfolio tracker for my LEGO collection — sharing it in case anyone else wants to track ROI

I got tired of losing track of what my LEGO collection is actually worth, so I built a free site that lets you track every set you own and shows real-time resale value, ROI, and which retired sets in your collection are appreciating fastest.

Free, no ads, no login required to browse. Sign-in is just for saving your collection across devices (no password — magic link to your email).

What's there:

  • Add any LEGO set + qty + what you paid → see current resale value, ROI %, total portfolio gain
  • Watchlist with price-drop alerts when sets you don't own go on sale
  • Hot Deals page with live retail prices across major retailers
  • Retiring Soon tracker with countdowns

bricktracker.net

Honest disclaimer: brand new, will probably break in places. If anyone tries it, please tell me what's broken or missing.
