The CardKingdom buylist is what they pay to buy cards from you, and it changes all the time. TCGSentry lets you look up any card's live buylist price and its full history, tracks the cards you care about, and flags the moment one climbs to a price worth selling at.
Or search any card to see its price history, best buylist, and sell signal. No account needed.
Take any card you own. Its buylist price moves constantly. There's where it usually sits, where it climbs to on a good week, and the rare ceiling it hits a couple of times a year. Sell at the wrong moment and you leave the difference behind. Across a whole collection, that difference is real money.
Illustrative example. Import your collection to see your own numbers.
Different stores pay different amounts for the same card, and it changes by the day. We check every buylist we track and quote you the highest. Then we show that payout as a share of what listing the card yourself would clear after fees, so you can see at a glance whether the cash today is worth taking.
Illustrative example. Your cards show their own live numbers.
When you sell to CardKingdom you sell into their buylist, the set of prices they are willing to pay for each card and condition. Those prices rise and fall with demand, reprints, bans, and tournament results. The buylist is the number that decides how much you actually get, which is why TCGSentry tracks it rather than retail.
Search any Magic card and TCGSentry shows its live CardKingdom buylist price, the full history of every change, and whether it is a sell or a hold right now. We check Star City Games and the marketplaces too, and always quote you the best. No account needed to look. Sign up when you want alerts on the cards you own, with a one-click path to the store paying the most.
TCGSentry watches every buylist price change all day and tells you when one of YOUR cards reaches a price worth selling at. An alert can watch CardKingdom on its own, or every buylist at once, so you only ever act when there is real money on the table, wherever it is.
Constantly. A card's buylist can change several times a week as demand shifts. TCGSentry records every change so you can see the history and get alerted when it matters.
Yes. Set a target on any card and choose which buylists to watch, or leave it on all of them, which is the default and picks up stores we add later. TCGSentry emails or pings you on Telegram the moment one of them reaches your price, tells you which store got there, and takes you to its cart.
No. CardKingdom is one of the buylists we track. We also check Star City Games, and we compare buylist payouts to marketplaces like TCGplayer and ManaPool after fees, then quote you the best. This page focuses on the CardKingdom buylist because it is what a lot of sellers search for.
No. TCGSentry is independent. We take part in the affiliate programs of the stores we link to, including CardKingdom, but we are not owned or operated by them. Pricing comes from public feeds.
Three steps. We do the watching, you do the selling.
Import from Moxfield, ManaBox, Archidekt, Deckbox, MTGGoldfish, TCGplayer, or a CSV in one go. We match every card and check it against the top buylists and the marketplaces for you.
Every card gets a clear Sell or Hold call and a target price. Then we watch those buylists for you, all day, every price change.
The moment a card hits its number at any buylist you are watching, you get an email or Telegram ping. It names the store that got there and takes you to its cart in one click. No spam, just the cards worth selling.
Import your collection in two minutes and see what it’s worth, which cards to sell, and when. Free to use.
