Price Spectre is an automated pricing agent for eBay sellers. Price Spectre automatically monitors your competitors' listings and reprices your own listings based on rules you've set. Dynamic pricing can give you an edge over the competition.

For each managed listing, Price Spectre requires search parameters to be defined. This is basically an advanced search similar to the one found on eBay. Price Spectre uses the listings found via the search parameters when updating your prices.

To make the setup process quicker, you can set default search parameters for everything except for keywords. If the item is in eBay's product catalog and you listed it using a UPC or ISBN number, then Price Spectre will automatically import this along with the item's condition. If you sell common items (media, books, etc.) you could potentially have every listing automatically set up for you at listing time.

When listing a new item, it will automatically appear within Price Spectre. If you have any default settings, they will then be applied to the listing.

When you list an item, we automatically try to match it with your ended listings. If we find a match, we'll use the same information you gave us for the original item. To take advantage of this feature, you must relist within 30 days and must use the same title. Note: If you are using a third-party tool to manage your listings, it may not properly relist your listings. If you find that your listings are not being matched on relist, enable the setting called 'Relaxed Relist'. This setting will assume the most recently listed item with the same title and SKU is the original listing regardless of whether eBay has it marked as the original or not. Do not use this setting if you have multiple listings with the same title and SKU.

Price Spectre does not enforce a single pricing strategy. Instead, it provides a flexible framework that allows sellers to define exactly how their prices should be calculated based on market conditions. At its core, Price Spectre evaluates competitor listings using your configured search parameters and then determines a target price according to the rules you've chosen. These rules can be as simple as pricing relative to the lowest competing offer, or as advanced as custom logic that accounts for factors such as competition depth, listing position, sales velocity, inventory levels, and time since the last price change. Price Spectre includes built-in pricing approaches for common strategies, but many sellers choose to create custom algorithms to fully tailor their pricing behavior. Custom algorithms are written in JavaScript and give you fine-grained control over how prices are calculated, when prices should change, and how edge cases (such as no competitors being found) are handled. This approach allows Price Spectre to support a wide range of selling styles — from aggressive competitive pricing to margin-focused or inventory-driven strategies — while adapting dynamically as market conditions change.

AlgoForge is Price Spectre's built-in assistant for creating, understanding, and refining custom pricing algorithms. Writing pricing logic can quickly become complex, especially when accounting for real-world factors like competitor behavior, inventory pressure, sales history, and edge cases. AlgoForge helps simplify this process by guiding you through algorithm design, explaining how different pricing decisions affect outcomes, and assisting with writing and reviewing JavaScript-based pricing logic. AlgoForge is designed to work directly with Price Spectre's pricing system, meaning it understands available data, supported functions, and platform-specific behaviors. Whether you're starting from a simple pricing idea or evolving an advanced strategy, AlgoForge helps you iterate faster and with more confidence — without requiring you to be an expert programmer.

Price Spectre requires that every managed item have a floor price set. Price Spectre will never set the price of your item below that amount. Floor prices should be set to the lowest price a seller feels comfortable selling their item.

Not necessarily. Price Spectre is designed to respond to market conditions, not blindly lower prices. While some pricing approaches compare your listing to lower-priced competitors, price changes are always constrained by your configured rules, such as floor prices, competition filters, and custom logic. Depending on demand, competition depth, and inventory pressure, prices may increase, decrease, or remain unchanged over time. Many sellers use Price Spectre to balance competitiveness with profitability — allowing prices to rise when competition weakens and adjust downward only when market conditions justify it. By continuously adapting to the market, Price Spectre helps optimize pricing decisions over time rather than pursuing short-term price cuts.

Managed listings have their prices adjusted several times per day. Premium points can be used to adjust repricing frequency to as often as once every 15 minutes. Standard repricing frequency is based on 4-hour intervals, though this time may change without notice.

No. Price Spectre gives you full control over how and when your prices are changed. You can choose to have Price Spectre automatically apply price updates based on your pricing rules, or you can use a manual review approach where pricing recommendations are generated but not applied until you approve them. This allows you to stay informed about market-driven price changes without committing to full automation. This flexibility is especially useful when testing new strategies, managing high-value listings, or maintaining tighter oversight during seasonal or promotional periods. You can mix automated and manual approaches across different listings, giving you precise control over how much automation you use.

Every new user is given a 14-day free trial to evaluate our service. See our fee schedule for a list of costs.

Premium points can be purchased by power users to unlock premium features of Price Spectre. Each premium feature comes with its own monthly cost in premium points. Premium features currently include repricing frequency, an exempt sellers search parameter, and performing multiple searches in a custom algorithm.

No, we use the eBay API which is the official method for third-party developers to access eBay accounts. You will only need to generate a token giving us authority to access your account during the linking process.

When creating an account with us, we will collect your name, email address, country, state, and postal code. All other information will be optional. It is highly recommended that you don't use your eBay password when creating your account.
