If you cannot keep the equipment, why would you pay one more dollar than the shipping cost?
If I go to the rental car company, I pay them a small fee for the use of the car on some time basis, day week or month. I surely don't pay them some portion of the price of the car and this fee.
The whole idea of paying even $99 for a unit in which you have no equity is senseless.
So, let me get this straight Jerry.
It's OK to pay $35 per day to rent a car for a week, but it would be senseless to pay $100 up front and $20 per day? Really?
