Really useful extension for eBay research. It makes it much faster to check potential profit, sold data, and competition without jumping between tabs. The side panel is clean, simple, and actually helps make quicker buy-or-pass decisions. Thank you!

Privy has completely streamlined my eBay sourcing workflow. Instead of spending 5–10 minutes manually checking sold listings, I get sell-through rate, competition data, and a profit estimate right on the listing page in under a minute. The buy/pass verdict keeps me disciplined when sourcing at car boots. Highly recommend.

Great tool — all the manual tasks that would take me hours to do are now completed with a click of a button. Plus the dashboard has stopped me using messy spreadsheets.

Privy helped me source products that actually sell. It gave me information that I used to take hours manually preparing. The founder was really helpful and eager for feedback so he could develop Privy to be the best it can for eBay sellers.

You're one bad buy away from losing money

You bought 20 units. Only sold 3.

Your margins looked great. But fees ate your profit.

You followed the hot product. But now everyone’s selling it.

There’s a better way.

What if you could see the future?

Not quite. But close enough.

While other sellers guess based on active listings, you’ll see what actually sold. What buyers actually paid. What margins actually look like after eBay takes its cut. It’s not magic. It’s just data they don’t have.

Great Opportunity

Your unfair advantage, disguised as a Chrome extension

41 units moved last month at £34.98 median

Demand is real — and this product keeps selling week after week. Not a one-hit wonder.

35.5% margin after all fees

£12.44 net on every unit. eBay fees, payment fees, shipping — already deducted. What you see is what you keep.

LOW competition — only 5 active listings

You found a gap. 38 monthly sales split between just 5 sellers. You can own a slice of this market today.

All this. On the product page. In 60 seconds.

Here’s what guessing is actually costing you

Monthly Cost of Guessing
Dead inventory sitting in your garage −£340
Products that didn’t sell as fast as expected −£180
Margins that looked good until fees hit −£95
Time wasted on manual research (15 hrs) −£225
Total monthly cost of guessing −£840
Guessing costs you
