@aynulhabib Maybe for a 20% off discount to me (the employer, in this example) I would pay your annual salary up front. Reminds me of the marshmallow test.
@aynulhabib Washers have very vigorous cycles and weigh much more than dryers, especially when full of water. This would create a top heavy, tip easy problem. Additionally, if the washing machine leaks, the water will destroy the dryer on it's way to the floor. Best solution is side by side.
