In the US with sale flyers from Home Building stores and other big retailers, one can find a new washer and dryer set for 450 to 499 dollars. This can take a few months waiting and hunting until the super sales are "happening".
With a Haier, the lowest here is a HLP21N or HLP23E; but these are super pulsating washers that are in the 220 dollar range for the lowest ones. The buyers of these are more often a dorm, condo or apartment user than a home owner.
Thus most will buy a new full 27" wide 3 cubic foot washer for 250 to 300 dollars; than buy a 220 dollar 1 cubic foot 18" pulsating machine.
Some local newspapers have regular adverts where a local repair type guy sells used washer and dryers in the 100 to 150 dollar range for each with delivery too. This gives the buyer a better "feel" since the seller is not just some single seller; its is a installer reselling the trade-in's that still have some life left in them.
Many folks like me value the cost too of having somebody home delivering the product, ie we do not have to mess with the whole hossing around and back break of buying and removing anothers washer.
Dryers here often rarely fail, folks will replace the old dryer so they have a "matched set of washers and dryers".
