[ TRUE PRICE CALCULATOR FOR MAC.BID ]

Stop guessing at checkout. Estimate your absolute final cost on MAC.BID in real-time before you place a bid.

Buying on MAC.BID is a great way to find deals, but the raw bid price doesn't tell the whole story. Between the 15% buyer's premium, $3.00 lot fee, $7.00 optional buyer assurance, and local sales tax, a $50 bid can quickly become a $68+ invoice at checkout.

This extension shows you your exact, fully itemized final cost directly on the bidding panel and product listings in real time.
