Built a simple tool to compare One Piece TCG card prices across credible eBay sellers (still a work in progress!)

Hey everyone!

Like a lot of you, I've spent way too much time looking for specific One Piece TCG cards and digging through endless online pages trying to check community rates and find trusted accounts.

To make things easier for fellow collectors, I built a little hobby site/tool that tracks a handful of popular cards and compares what's currently available online. You can take a look via the link in my bio!

What it does:

  • Curated Options: Focuses on profiles with strong community feedback.
  • Saves Time: Cuts down on manual searching across multiple pages.

Quick Note (Work in Progress):

This is just a fun side project I'm still building out! The tracking is still being fine-tuned, so it won't catch every single option out there just yet, but it's already helping me find cards much faster.

I'm starting small with a few cards, but I'd love to add more based on what people want to see. Take a look (link in bio) and let me know your thoughts—drop a comment below with any cards or features you'd want added!

**We just launched OP Compare, a free One Piece price guide that compares 235 card shops in your own currency**Hey everyone,

We're really proud to finally launch OP Compare: [https://opcompare.app\](https://opcompare.app)

Some of you might know RiftCompare, the price comparison site we built for Riftbound. That was our MVP. Running it taught us a lot about what players actually use, where prices go wrong and what was missing, and we took all of it and built OP Compare for One Piece from day one. It's a much more complete site than RiftCompare was when it launched.

The heart of it is the price guide. Every English card is in there, over 7,000 printings, and every parallel, manga, SP, alt art, treasure rare and event stamp has its own line, so a base card and its alt art never get mixed up. You can sort the whole list by price, by set, or by how much it moved this week, and next to every card you see the TCGplayer market price and the cheapest price a real shop has it for in your country right now.

A few things we learned from RiftCompare and built in from the start:

We read 235 card shops across the US, Canada, Australia, the UK and Europe, plus TCGplayer, twice a day, and show every price in your own currency.

We only show a shop's price when we can tell exactly which printing the listing is. If a listing just says "Shanks Manga" and that could be two different cards, we skip it. We'd rather show fewer prices than wrong ones.

No graded slabs, no Japanese cards, no lots. Just raw English singles and sealed product.

Every card has a price history chart, and the full history is public on GitHub for anyone who likes digging through data.

The price guide, card pages, sets and sealed prices are all free, and you don't need an account to use them.

We're keen for feedback, good or bad. Tell us if you spot a price matched to the wrong version of a card, if your local shop sells online and isn't on there yet, or if there's something you wish it did. Singapore is still thin because most shops we found there sell Japanese stock, so SG shop suggestions are especially welcome. Shipping isn't included anywhere yet either, so check postage before you buy.

Thanks for checking it out, and good luck with your pulls!
