This is an early-access / beta release of Guppy.

Features are actively shipping and evolving. Some functionality requires your browser to be open and logged in, and certain tools should be monitored closely while they mature.

General Requirements

• Your desktop computer and browser must be open for execution-based features to run (for now).
• You must be logged into the relevant retailer account (eBay, Walmart, etc.).
• A valid credit card must already be saved as the default payment method on that account.
• The features mentioned below are in the desktop extension. We’re mostly prioritizing development of the desktop extension
• Only USA retailers are supported at the moment.

If Guppy cannot access an authenticated, ready-to-checkout session, it will not be able to complete actions.

Current Premium Features:

Product Watch Missions

• A Create Mission card appears in the sidebar on supported retailer product pages.
• You will be able to set up a “mission” with a max price for the given product with a trigger action of “Notify” or “Auto Checkout”
• Note: Your target price must account for tax, shipping, etc. If the total price exceeds your target at any point the mission will fail.
• When enabled, the extension will detect when the product is both in stock and at or below the target price and the mission will be triggered.
• Missions currently support Target, Walmart, BestBuy, Gamestop and EBgames.
