FAQ

Questions before you install

Is it free?

Yes. Every feature is free, with no trial and no blurred numbers. It does not need a 3Dsellers account or subscription.

Do I need a 3Dsellers account?

No. The research extension works without one and there is nothing to log in to. You do need to be signed in to eBay, because eBay only shows purchase history to signed-in users.

Does it work on eBay.co.uk, eBay.com.au and eBay.ca?

Yes. It runs on 19 eBay sites: eBay.com, eBay.co.uk, eBay.ca, eBay.com.au, eBay.de, eBay.fr, eBay.it, eBay.es, eBay.at, eBay.ch, eBay.be, eBay.nl, eBay.ie, eBay.pl, eBay.com.sg, eBay.com.hk, eBay.com.my, eBay.ph and eBay.in.

Where does the data come from?

From eBay's own purchase-history page for the listing, fetched by your browser. eBay lists the last 100 purchases, and only for multi-quantity listings with sales. Single-quantity listings show the lifetime sold count instead.

Does it send my research to 3Dsellers?

No. The numbers are computed in your browser, and titles, seller names and prices are not sent to 3Dsellers. Saved products and tracked sellers stay in Chrome on your computer. The extension sends anonymous usage events and error reports so bugs can be fixed.

What is 3Dsellers, and do I need it?

You do not need it for research. 3Dsellers is an eBay selling manager for listings, bulk edits, orders and messages. When you find a product worth selling, the free 3Dsellers Product Importer copies it into your catalog in one click. 3Dsellers starts with a free 7-day trial, no credit card required.
