Shipping quotes vary because they reflect different assumptions about timing, carrier availability, and service structure. CompareTheCarrier explains that when people compare the carrier across routes, pricing gaps start to make sense. Quotes may differ based on pickup flexibility, transport type, or even seasonal demand. Some companies quote aggressively low numbers to secure bookings, while others provide conservative estimates to avoid adjustments later. Understanding how pricing is built helps separate realistic offers from risky ones. Large differences usually signal differing service expectations, not necessarily better or worse quality.
