The problem

You’re losing deals in the final seconds.

Manual bidding fails when timing matters most. Refreshing, clicking, and hoping does not work against fast bidders, automated tools, and cross-marketplace auction chaos.

HighBiddr removes the guesswork. You set the max bid and exact timing once, then manage eBay, GunBroker, and ShopGoodwill snipes from one place.

Supported marketplaces

One sniping workflow across three auction sites.

HighBiddr now supports scheduled snipes on eBay, GunBroker, and ShopGoodwill, with marketplace labels, live auction context, and one unified popup.

eBay

Classic auction sniping

Schedule final-second bids for collectibles, coins, watches, parts, and the everyday eBay auctions you track.

GunBroker

High-stakes timing

Keep GunBroker snipes in the same dashboard with custom timing, live price context, and clear marketplace labels.

ShopGoodwill

Thrift finds, automated

Add ShopGoodwill auctions to your schedule for electronics, jewelry, collectibles, and estate-sale finds.
