As a full-time reseller, I've spent a lot of time analyzing what types of items sell quickly and which ones take longer to move. From my experience using platforms like Poshmark, eBay, Etsy, and Mercari, some trends stand out that might help fellow resellers or anyone curious about resale. For example, smaller accessories like the Anthropologie Eclipse leather earrings I sold on Poshmark moved surprisingly fast—they sold within eight days and yielded about $7 profit. Accessories tend to be impulse buys and are usually priced lower, making them attractive for quicker sales. On the other hand, larger or higher-priced items like the Ralph Lauren men's navy wool blazer I sold on eBay took longer—over 100 days—but generated a higher profit margin. These items often appeal to more specific buyers and require patience. The blazer sold for $45 with additional shipping, resulting in considerable profit after fees. One tip I've learned is to price competitively and provide detailed descriptions and quality photos regardless of the platform. Also, using popular resale platforms like eBay and Poshmark can expand your audience. Curtsy and Depop are also options, but each has its own buyer demographics and best-selling categories. Tracking your sales performance on each platform helps identify which products and categories resonate most with buyers. For me, leather accessories, brand-name clothing, and vintage pieces are consistently strong sellers. Patience is key; some items sell quickly, while others might take longer but result in higher profits. Sharing my journey helps me stay motivated and connected to the reseller community. If you’re starting out, focus on your niche and learn from your sales data to optimize what you list and where. Overall, selling online requires understanding your market and balancing fast-moving items with higher-value pieces for the best results.
