There are a ton of shady movers in the industry trying to make a buck by cutting down overhead. They’ll move your stuff into a storage unit until they can combine it with other clients’ stuff into a larger (semi) truck headed in the same direction.

This level of coordination requires quite a network to work smoothly which most don’t have, hence the excessive delays and demands for more money. Possibly the worst part is that they’re staffed by the absolute cheapest day-laborers available who probably don’t care about treating your property with respect.
