Hero Stuff analyzes thousands of recent sales across multiple marketplaces to provide you with an accurate, real-time price range for your item. We take into account the condition, completeness, and current market trends.

The most significant factors are the condition of the item, whether you have the original box and accessories, and the current market demand. Items in "Like New" or "Mint" condition typically sell for more.

The best places to sell depend on your item. Generally, eBay, Facebook Marketplace, and Mercari are top choices for electronics and collectibles. Hero Stuff helps you list across these platforms efficiently.

Check recent sold listings rather than active asking prices. Hero Stuff does this automatically for you, filtering out outliers to give you a realistic expectation of what your item will sell for.

An item is considered "New" only if it is still factory sealed. Having the original packaging and accessories can increase resale value by 15-20% compared to the loose item alone, as it appeals to collectors and gift buyers.
