FairPullHow we price cards
Every price on FairPull is computed by the same deterministic rules, for every card and every user. This page explains exactly how, because a price you cannot inspect is a price you should not trust.
Where the data comes from
- TCGplayer market prices, refreshed from daily data feeds, per printing (Holo, Reverse Holo, 1st Edition, and so on).
- eBay sold sales for the same card, so the number reflects what buyers actually paid, not what sellers are asking.
- Listings we observe ourselves: the cheapest live listing we have seen for the printing in the last 30 days.
The FairPull Market Value
The headline number anchors on the TCGplayer market price for the exact printing. The eBay sold price is a cross-check, not an input: when it agrees with the anchor within 25 percent we mark the value high confidence; between 25 and 60 percent apart it stays medium; beyond 60 percent we mark it low. A single outlier sale can lower our confidence, but it can never corrupt the displayed number.
Condition and graded prices
Raw cards are priced per condition, from Near Mint through Damaged, using real per-condition sales history where it exists. Graded slabs are priced per grade and grading company from graded sales data. A slab is never priced from raw-card numbers. When we lack data for the exact condition, we fall back to the Near Mint price and flag it visibly.
What the markers mean
A tilde and an amber tone always mean the same thing: this number is an estimate, built on thin data or a stated fallback. Hover or tap the marker to see why. Estimated prices are never used for deal alerts.
What a deal percentage means
We compare a listing's full buyer cost, shipping included, against our market value for that printing and condition. "32% below market" means exactly that, against the number you can inspect on the card's page.
What we do not do
- No AI guessing. Listing matching and pricing are rule-based and reproducible.
- No asking-price inflation. Sold data and market anchors only.
- No hidden adjustments. The same rules run for everyone.
How fresh is it
Catalog prices refresh daily from the bulk feeds. Price history accrues a point whenever a card's market actually moves, and eBay listings shown in the app carry an "as of" timestamp.
Questions we get
Where do FairPull prices come from?
Three places. TCGplayer market prices from daily data feeds, recent eBay sold sales for the same card, and the cheapest live listing we have actually observed ourselves in the last 30 days.
What is the FairPull Market Value?
It anchors on the TCGplayer market price for the exact printing. The eBay sold price acts as a cross-check: when the two agree within 25 percent we mark the value high confidence, and when they disagree by more than 60 percent we mark it low confidence. The cross-check never changes the number itself, only how much we tell you to trust it.
What does the tilde or amber marker mean?
It flags an estimate. Either the sales data behind the number is thin, or we had to fall back to a nearby price, like valuing a lightly played card at its Near Mint price because no condition-specific sales exist yet. We show the fallback visibly instead of hiding it.
What does the deal percentage mean?
The listing's full buyer cost, including shipping, compared to our market value for that exact printing and condition. A 30 percent deal means the asking total is 30 percent below the market value.
Does FairPull use AI to guess prices?
No. Every price is computed by the same deterministic rules for everyone: no AI guessing, no asking-price inflation, no hidden adjustments. If we cannot price something reliably, we say so instead of inventing a number.
