Selling Online
Without the Overwhelm.
eBay, Mercari, Poshmark — online platforms open your items up to the entire country. Here's how to think about them.
Local selling is great for bigger items. But for everything else — the smaller stuff, the brand-name finds, the things with real resale value — online platforms are where the money is.
The difference between selling locally and selling online is reach. Locally, you're selling to whoever happens to be in your city that day. Online, you're selling to the entire country. Someone in Florida wants exactly what you have sitting in a box in Tennessee. That's the opportunity.
The platforms feel overwhelming at first. Too many fields, too many options. But once you understand what each one is good for, it gets simple fast.
The Main Online Platforms
eBay — The Biggest Audience
eBay has been around forever and has the largest buyer base of any resale platform. It's great for electronics, collectibles, brand-name items, and anything with a clear resale market. The learning curve feels steep but it's mostly about knowing which fields actually matter.
Mercari — Underrated & Easier
Mercari is simpler than eBay and has less competition, which means your listings stand out more. Great for home goods, beauty products, clothing, and general items. Lower barrier to entry and a surprisingly active buyer base.
Poshmark — Best for Clothing & Soft Goods
If your box has clothing, shoes, bags, or accessories, Poshmark is built for exactly that. The platform has a strong community of active buyers specifically looking for those categories. Worth having an account just for that.
You don't have to pick just one. List the same item on multiple platforms and take it down when it sells. More platforms means more buyers means faster sales.
Stop Guessing What Things Are Worth
The single biggest mistake online sellers make is pricing from instinct. They look at an item, think "this feels like a $20 thing," and list it at $20.
Here's the thing — you don't have to guess. Every major platform shows you what similar items have actually sold for recently. Not what other sellers are asking. What buyers actually paid.
That one shift — checking what sold before you price — is the difference between items that sit for months and items that sell in days. It's the foundation of every good online listing strategy.
How to Check What Things Actually Sell For
On eBay, search for your item and then filter the results to show only Sold Listings. This shows you real completed sales — what buyers actually paid, not what sellers hope to get.
It takes 30 seconds and will immediately tell you whether to price something at $8 or $40. Use it every single time before you list anything online.
