Earnings vary by category and effort. Our top sellers earn $2,000+ monthly, while casual sellers typically make $200-500. Electronics, fashion, and collectibles tend to perform best.

Yes, but we make it easy! You can print discounted shipping labels directly from your dashboard. We support USPS, UPS, and FedEx with tracking included.
