Buying and downloading
How do I get my files?
Instantly. After checkout you land on a download page, and the same links arrive by email. Downloads stay available in your account, so you can come back for updates.
Do the spreadsheets work in Google Sheets?
Yes. Open Google Sheets, choose File → Import → Upload, pick the .xlsx file and choose "Replace spreadsheet". Dropdowns, formulas and colour coding carry over. They also work in Excel 2019 or later, Excel 365 and LibreOffice 7.4 or later.
Are updates free?
Yes, for life. When we refresh a Set Value Sheet with new prices or update a fee table, the new version appears at your original download link and you get an email.
Can I get a refund?
Before you download: yes, within 14 days. After downloading: we fix errors and re-issue files, and we refund if a product does not do what its page says. Full details are in the refund policy.
The data
Where do the prices come from?
TCGplayer market prices and Cardmarket averages, collected daily through third-party APIs. Every file states its data date on the first page and in the footer.
Why does a price in my sheet differ from what I see on TCGplayer right now?
Prices move daily and the sheet shows the price on its data date. Set Value Sheets are refreshed monthly; the CSV that comes with each sheet has the exact date per row.
Do you include graded card prices?
Not yet in the automated products. The Grading ROI Calculator asks you to enter recent sold prices for the graded card, because graded comps vary a lot by grade and by week and you should use the freshest ones. Our guides show exactly how to find them in two minutes.
Why are there no card images?
Card artwork belongs to its owners and we do not reproduce it. Cards are identified by name, number and set.
Grading
Which grading company do you recommend?
None. The calculator shows the maths for PSA, CGC, TAG and Beckett with their current fees and turnaround times, and tells you the cheapest active tier that fits your card's value. As of September 2026 PSA's Value tiers are paused, so its cheapest active option is Regular at $79.99, which changes the answer for most cards under about $300.
How do I know my chance of a 10?
Start from the card's PSA population report, discount it a little for survivorship, then adjust for centering, edges and surface under a loupe. The Gem Rate Guide tab in the calculator walks through it with reference ranges.
Is this investment advice?
No. These are decision aids that show the arithmetic. Collectible prices fall as well as rise, and every decision is yours.
