Top Questions Resellers Ask on Poshmark, eBay, and Other Platforms – Answered

Whether you’re just starting your reselling journey or looking to scale your business, you’ll quickly discover that platforms like Poshmark, eBay, Mercari, Depop, and Amazon FBA each have their own quirks. To help you out, we’ve rounded up the most frequently asked reseller questions — and provided answers and actionable tips to boost your sales.

1. What’s the Best Platform to Start Reselling?

Answer: It depends on what you’re selling.

Poshmark: Great for fashion, accessories, and home décor.
eBay: Best for collectibles, electronics, and a wide variety of items.
Mercari: A mix between Poshmark and eBay — simple, beginner-friendly, and less competitive.
Depop: Popular with younger buyers looking for vintage or trendy items.
Amazon FBA: Ideal for bulk inventory, retail arbitrage, or wholesale products.

Recommendation: Start with one platform that matches your product niche. Once you’ve mastered it, cross-list to expand reach.

2. Where Do Resellers Source Their Inventory?

Answer: Some of the most common sourcing methods include:

Thrift stores & garage sales – Great for unique finds at low cost.
Liquidation pallets – Bulk lots of overstock, returns, or shelf pulls.
Retail arbitrage – Buying clearance items from big-box stores and flipping online.
Wholesale suppliers – Reliable way to scale once you know your niche.

Recommendation: If you’re starting small, begin with thrift stores and clearance sections. For scaling, explore liquidation pallets and wholesale distributors.

3. How Do I Price My Items?

Answer: Pricing is a balance between competitiveness and profit margin.

On eBay, check “Sold” listings to see what buyers are actually paying.
On Poshmark, factor in the platform’s 20% fee.
On Amazon, use tools like Keepa or SellerAmp to track pricing trends.

Recommendation: Always price slightly higher than your target profit, leaving room for offers and discounts.

4. Should I Offer Free Shipping?

Answer: It depends on the platform and your margins.

eBay: Free shipping often boosts visibility in search.
Poshmark: Buyers pay shipping, but offering discounted shipping can attract sales.
Mercari: Many buyers expect free or low-cost shipping.

Recommendation: Test both strategies. If you build shipping into your price, you can advertise “free shipping” without cutting into your margins.

5. How Can I Get More Sales?

Answer: Success comes from visibility, trust, and customer service.

Optimize listings with keywords, clear titles, and detailed descriptions.
Use high-quality photos with good lighting and multiple angles.
Engage with the community — on Poshmark, share closets; on eBay, respond quickly to offers and messages.
Offer bundles or discounts to encourage larger purchases.

Recommendation: Think of your reseller account as a storefront. The more professional and trustworthy you look, the more buyers will return.

6. What Are the Biggest Mistakes to Avoid?

Answer: New resellers often fall into these traps:

Overpaying for inventory without checking resale value.
Neglecting fees and shipping costs in their profit calculations.
Stockpiling unsold inventory without testing demand.
Using poor photos or vague item descriptions.

Recommendation: Research before you buy, track all costs, and reinvest profits into proven niches.

7. How Do I Scale My Reselling Business?

Answer: Scaling is about efficiency and diversification.

Cross-list across multiple platforms using tools like Vendoo or List Perfectly.
Outsource tasks like photographing or shipping once sales grow.
Reinvest profits into larger inventory sources like liquidation pallets or wholesale.
Track performance with spreadsheets or reseller-specific software.

Recommendation: Don’t rush. Focus on consistency first, then grow strategically.
