Cardslot

Cardslot is an Android and iOS app for following Nintendo Switch and Switch 2 eShop prices, ranking deals and receiving sale alerts. Its default deal score takes into account discount percentage, regular price and eShop sales rank. Price information comes from public Nintendo eShop data read several times a day; the eShop price at purchase is authoritative. Users can track games across fourteen storefronts, including ten European storefronts and the United States, Canada, Mexico and Brazil. Alerts cover price drops and a reminder the day before a sale ends. The app sends at most one alert per day between 9:00 and 21:00 local time, though its terms describe alerts as best-effort and do not guarantee timely delivery. A sale calendar displays end times and a histogram of deals ending over the next fifteen days. The free version includes the full deal list, search, all sorts and one tracked game. The one-time Full version costs $3.99, paid once and adds unlimited tracked games, price history and additional filters. Watchlists are stored on the device and on the maker's server for restoration and alert computation.

Cardslot combines deal sorting, sale reminders and a calendar for Nintendo eShop purchases. The free version is limited to one tracked game; the $3.99, paid once Full version adds price history and more tracking.

Cardslot suits Nintendo Switch and Switch 2 owners who want to monitor eShop prices across supported storefronts. The free version is limited to one tracked game.

Cardslot is a focused tracker for Nintendo Switch and Switch 2 digital-store prices. It suits players who shop in its supported regions and want sale timing, deal sorting, and watchlist reminders in one mobile app. The main trade-off is a strict free-plan watchlist limit and alerts that are useful but not guaranteed to arrive on time.

Overview

Cardslot reads public Nintendo eShop data several times each day, then ranks offers using discount percentage, regular price, and eShop sales rank. That scoring is practical for finding prominent bargains without manually comparing every listing, but it remains a discovery aid rather than a purchase guarantee: Nintendo’s price at checkout is the authoritative amount, so verify it before paying.

The service covers fourteen storefronts: ten in Europe, along with the United States, Canada, Mexico, and Brazil. Regional price tracking is useful for shoppers who legitimately compare those markets, while the absence of physical-store tracking keeps Cardslot firmly focused on digital console purchases. English, French, Spanish, Italian, Portuguese, and German interfaces broaden its appeal across the covered countries.

Key features

Alerts and sale planning

Watchlisted games can trigger a price-drop alert and a reminder one day before a sale ends. Cardslot sends no more than one alert per day, during a 9:00–21:00 local-time window. This controlled schedule is less intrusive than an alert for every small change, but it is not an instant price-monitoring feed. The terms call alerts best-effort and do not promise that generation or delivery will be timely, so time-sensitive purchases should not depend on a notification arriving.

The sale calendar adds useful context by showing sale end times and a histogram of deal endings over the next fifteen days. It helps identify crowded end-of-sale periods and plan purchases before offers disappear, rather than merely presenting a static list of discounts.

Data and privacy

Watchlists are stored on the device and on Cardslot’s server so they can be restored and used for alert computation, under a random installation identifier. Its database and server logs are hosted on AWS in Paris, while the application server runs on OVH in France. AWS, OVH, and RevenueCat are identified as processors; Apple and Google handle store purchases and push delivery under their own policies. That arrangement gives the app a clear operational purpose for synchronized watchlists, though users should understand that watchlist data leaves the device.

Pricing

The Free plan costs nothing and includes the full deal list and search, all sorting options, one tracked game, and the same alert types as the paid tier. It is a sensible way to evaluate Cardslot or follow one priority title, but a broader collection quickly runs into the single-game cap. There is no free trial because the core plan is already free.

The Full version costs $3.99 once as a one-time in-app purchase, with the price shown by your store. It removes the tracked-game limit and adds price history and additional filters. This is a low-friction upgrade for players maintaining a substantial watchlist or wanting to judge an offer against past prices. It does not turn Cardslot into a physical-retail tracker, and the alert limitations still apply.

Platforms

Cardslot is available on Android and iOS. Its scope is console storefront coverage rather than desktop web or API access, making it best suited to shoppers who want a phone-based companion while browsing Nintendo eShop deals.

Who it's for

Choose Cardslot if you primarily buy Switch or Switch 2 games digitally, live in one of the fourteen supported storefronts, and value a calendar plus a manageable stream of sale reminders. The Full version fits collectors and frequent buyers with more than one game to monitor. It is a weaker choice for physical-game shoppers, users outside the listed regions, or anyone requiring guaranteed real-time alerts.

Pros and cons

• Pros: Deal ranking combines discount, regular price, and sales rank; the calendar exposes sale end dates and upcoming deal-ending patterns; fourteen storefronts and six languages support regional shoppers; the one-time Full purchase avoids a recurring subscription.
• Cons: The free plan tracks only one game; alerts are capped at one per day and are explicitly best-effort; coverage excludes physical stores; checkout prices can differ from app data because Nintendo’s eShop price is final.

Verdict

Cardslot is a strong match for Nintendo digital shoppers who want ranked deals, sale-end planning, and a simple watchlist. Its $3.99 one-time Full upgrade is worthwhile once one tracked game is not enough, especially for users who value price history. Look elsewhere if you need physical-store prices, wider platform coverage, or guaranteed immediate notifications.
