📋 About This Mod

CardBay adds a card marketplace to your phone, buy and sell cards through listings and auctions. Pack them at the packing station. A full market of singles and slabs pulled from every expansion you have installed

Your shop just went online

CardBay puts a real online card marketplace on the phone. Every morning it fills up with fresh listings from every expansion you have installed: raw singles and graded slabs, at fixed prices or in live auctions against rival bidders who want them as badly as you do. Sell your own cards to collectors, then pack every sale by hand at your Packing Station. It is built for the mid and late game: a way to hunt the rare cards and high-grade slabs your shop never pulls, and to turn the expensive ones you do have into money.

Buying

A fresh market every morning

Around 75 new listings a day, drawn from your whole card library. Listings under $1,000 last a single day; bigger lots stay two or three days and are flagged LAST DAY on their final morning. Everything is priced against the card's real market value, so a bargain is a bargain.

Find the one you are after

Listings are a grid of tiles drawn with the game's own card rendering, so foils, slabs and modded sets all look right. Filter the market by:

  • []Listing type: everything, Buy It Now, or auctions[/]

    []Price: under $100, $100 to 1k, $1k to 10k, $10k and up[/]

    []Grade: any, raw only, graded only, or one exact grade[/]

    []Card game: every expansion on the market today[/]

    []Collection: cards you do not own yet, or ones you already do[/]

    Know exactly what you are buying

    Every listing opens to a full page with the card shown large, plus:

    • []Market value, and a % BELOW MARKET badge when the price sits under it[/]

      []In your album: how many copies you already own[/]

      []The room: for auctions, how many rival bidders will turn up[/]

      []Condition, card game, days remaining, and the total including fees[/]

      Buy It Now, no drama

      Fixed-price listings are yours in one confirmation showing the price, the buyer's fee and the total. Cannot afford it yet? The button tells you how much more you need.

      Live auctions with real tension

      Auctions run in real time, from the listing page, whenever you choose to start one.

      • []Lots open at 45 to 70% of market value, so a good price is within reach[/]

        []A six-second clock that resets on every bid, drawn as a ring that empties as it runs out[/]

        []Two ways to raise: a small bid at +2%, or a big one at +8% to scare the room off[/]

        []GOING ONCE, GOING TWICE and FINAL CALL as it closes[/]

        []A result card when you win, with the lot kept on screen until you leave[/]

        Rivals who bid like people

        Each auction draws up to four rivals, depending on the card's grade, foil and value. Every one of them has a hidden maximum and a personality: the quick responder, the early big raiser, the one who pays over the odds, and the sniper who waits until the final seconds to place one last bid. Rivals answer each other fast, hesitate when you lead, and give up when they are beaten. Cheap lots get bid further past market than expensive ones.

        Slabs, if you grade

        With Grading Overhaul installed, CardBay lists PSA and Beckett slabs, half grades and Black Labels included, priced with Grading Overhaul's own multiplier tables. Slab frequency follows value: cheap cards are mostly raw, valuable ones mostly graded. The base game's grading service is listed too and can be switched off in the F1 menu.

        The Exclusive Auction

        Every few days one headline lot is announced the day before it lists: a blacked-out slab with its grade, its expansion and an estimated value range. The morning it goes live it is unveiled in a popup with a button straight to the listing, it leads the market with a gold border, and the header button jumps to it. Always an auction, never two days in a row.

        Delivered with the morning boxes

        Purchases arrive in the game's own package box the next morning, a whole day's buying in one box.

        Selling

        Put your cards in front of collectors

        The SELL tab shows your album, most valuable first, beside your eight listing slots. A listed card leaves your album until it sells or comes back to you.

        []Buy It Now: name your price. Cheaper sells faster. Unsold after 7 days, it comes back.[/]

        []Auction: 1, 3 or 5 days. Longer auctions usually end higher.[/]

        []Bids arrive through the day and you can watch them on the listing's page[/]

        [*]Cards sell for close to
