CardWatch TCG is an eBay listing monitoring and alerting tool for trading card game (TCG) collectors. The service scans eBay for new listings matching your watchlist criteria and sends you notifications. CardWatch TCG also provides market value data sourced from third-party providers and eBay sold listings.
CardWatch does not provide financial advice, investment advice, or trading recommendations. All market values, estimated profits, pricing data, and grading information displayed on CardWatch are for informational and educational purposes only. They should not be interpreted as recommendations to buy, sell, or hold any trading card or collectible.
You are solely responsible for your own purchasing, selling, and grading decisions. CardWatch makes no representation that any particular transaction will result in profit or avoid loss.
CardWatch does not guarantee any financial outcome, profit, or return on investment. Past examples, estimated profits, potential ROI figures, and market data shown on the site are illustrative only and do not guarantee future results. Actual results depend on numerous factors including market conditions, card condition, timing, buyer demand, grading outcomes, and fees.
Any example scenarios, profit calculations, or ROI figures presented on CardWatch are hypothetical illustrations and should not be relied upon as predictions of actual results.
Market values displayed on CardWatch are sourced from third-party providers and may not reflect current or actual selling prices. Prices can change rapidly and may differ from what you actually receive when selling a card. CardWatch is not responsible for the accuracy of third-party pricing data.
We recommend verifying all pricing information by reviewing recent sold listings on eBay or other marketplaces before making any purchasing decision.
Grading standards, grading cost estimates, and PSA-related information provided on CardWatch are for reference only. CardWatch does not guarantee or predict the outcome of any card grading submission. Professional card grading is subjective, and actual grades assigned by PSA or other grading companies may differ from expectations. Grading fees referenced on CardWatch are approximate and subject to change by the grading company.
The estimated profit calculator is a guide only and should not be used as a definitive pricing tool. Calculations are based on current market data, user-configured fee estimates, and approximate grading costs. Actual profits or losses will vary based on final sale price, actual fees charged, grading results, shipping costs, and other factors. Users should conduct their own research before making purchasing decisions.
