The delivery fee is a significant fraction of the total cost of a modern dryer in the US. Saving a little money by getting crappier dryers will likely have a larger total cost because of the delivery fees, and also the cost of your time in taking time off from work to accept delivery.
WTF? We're talking about real dryers here, not dorm-sized dryers that you can dry maybe 2 shirts in.
However, if you select the Samsung 7.5cf dryer, it also has free delivery. Of course, this is built into the price, and $550 for an appliance isn't pocket change.
