About TCG UnderComp

TCG UnderComp is a small, independent project run by a trading card collector. It finds Pokémon, One Piece, Magic: The Gathering and Yu-Gi-Oh! cards that are listed for sale below what the same card has recently sold for, and posts them for free.

Why "UnderComp"

Collectors call recent sold prices "comps", short for comparables. A card listed under its comps is a card listed under what it really sells for. That is the only thing we look for.

What we do

• Check new fixed-price listings every day.
• Match each one to the exact same card: set, number, language, grade and grading company.
• Compare the price, including shipping, with the median of that card's recent real sales.
• Post the ones that are well under, on this site and by email, with Telegram and Discord to follow.

What we don't do

• We don't sell cards, hold stock or take part in any sale. Every deal links to the seller's own listing.
• We don't give investment advice. A card being cheap today says nothing about its price next year.
• We don't take payment from sellers to feature their listings.

Where we are now

The site is new. The scanner is in its test week, and the daily deals and news will appear on the home page when it goes live. Until then nothing on this site is presented as a live listing.

How the site is paid for

We may earn a commission from eBay links. See the affiliate disclosure.
