Common Facebook Marketplace negotiation mistakes
- ×Treating the listing price as the final accepted sale price.
- ×Accepting buyer offers without recalculating profit after item cost.
- ×Forgetting delivery, fuel, parking, tolls, or pickup effort.
- ×Ignoring payment processing or shipping fees when checkout applies.
- ×Dropping price repeatedly without protecting a minimum acceptable offer.
- ×Comparing against active listings instead of realistic local sold prices.
Understanding your negotiation results
Strong: The accepted price leaves strong room for negotiation, delivery, and normal local marketplace variation.
Healthy: The buyer offer appears workable under the current cost and fee assumptions.
Tight: The offer may still work, but delivery, shipping, lower counteroffers, or fee changes could reduce profit quickly.
Losing Money: The accepted offer would not cover all entered costs and fees.
