Win more eBay auctions with less effort, avoid bidding wars, save time and money!


This extension provides a local eBay auction sniping feature in a web browser.
It will automate snipe bidding on your behalf just before the end of auction.

Unlike other sniper applications this extension doesn't need your eBay password so it won't be disclosed on any server. Your eBay account is safe and secure.
All needed is an opened web browser tab with an active ebay session (this tab doesn't need to be visible).

PowerSniper comes with a free and a premium version.

Check out differences here.
