What Is Selling on Whatnot?
What if we told you there’s a way to sell products live, create hype in real-time, and build a loyal audience who come back to buy again and again? That’s exactly what Whatnot offers.
It’s essentially live-stream selling—think eBay meets TikTok Live. You host shows, auction items (often starting at £1), and viewers bid in real time.
Sellers in the UK are making anywhere from £100 to £1,000+ per session once they get momentum. You also get a bonus between £10-200 when you sign up here.
How Does It Work?
Here’s the basic process to get started:
Apply as a seller - You’ll need to apply and get approved to sell on Whatnot
Set up your profile - Choose your niche (cards, clothes, collectibles, etc.) and build a simple storefront
Schedule a live show - Pick a time, list your items, and promote your stream
Go live and sell - Auction items, engage with chat, and ship orders after the show
What Can You Sell?
Some of the best-performing niches right now:
✅ Trading cards (Pokémon, sports cards)
✅ Vintage & streetwear clothing
✅ Electronics & gadgets
✅ Funko Pops & collectibles
✅ Jewellery & watches

💡 Tip: Boring products don’t sell well live. You want items that are visual, collectible or exciting.

How to Source Products
This is where most people win or lose.
Top sourcing methods:
1. Charity shops / car boot sales
Cheap stock with resale potential
Great for clothing & collectibles
2. Wholesale / bulk buying
Buy low, sell across multiple auctions
Works well for bundles
3. Clearance / retail arbitrage
Tesco, B&M, TK Maxx etc.
Flip discounted items
4. Your own unused items
Easiest way to start with £0 risk
The goal: buy low enough that even a £1 start can still be profitable long-term

FAQ’s
-
Yes—if you’re willing to put the time in. Early on, it can feel slow, but once you build a following and repeat buyers, it can become a very strong side hustle. The key is consistency and sourcing products with margin.
-
No. You can start by selling items you already own (clothes, collectibles, unused tech). This is actually the best way to learn the platform with zero risk before reinvesting profits into stock.
-
You can start with £0 if you sell your own items. Realistically, £50–£200 is enough to begin sourcing stock and testing what sells.
-
Items that are visual, collectible or exciting perform best. This includes trading cards, vintage clothing, bundles, collectibles and anything with resale hype. Generic or boring products tend to struggle.
-
Yes. If you overpay for stock or your items sell too cheaply, you can lose money. This is why sourcing is crucial—buy low enough that even £1 starts work in your favour over time.
-
Individually, some items may sell below value—but across a full show, bidding wars, bundles and engaged viewers typically balance things out. The strategy is to build momentum and average profit across multiple sales, not rely on one item.
-
At minimum:
A smartphone
Stable internet connection
Basic lighting (natural light or ring light)
Better setup = better conversions, so improving lighting and audio over time helps.
-
Most successful shows run between 1–3 hours. Short shows can work, but longer streams give more time to build an audience and increase sales.
-
Start by promoting your show in advance (social media, communities), use £1 starts to attract people, and stay consistent. Your first few shows may be quiet—but momentum builds over time.
-
Yes. If you’re making money consistently, it counts as income. You may need to register as self-employed and declare earnings to HM Revenue and Customs.
-
Absolutely. Most sellers start part-time alongside work. Even 1–2 shows per week can generate decent extra income once established.
-
Typically a few weeks to a few months. Growth depends on consistency, niche and how engaging your shows are. The sellers who stick with it are the ones who usually see results.
