Let’s say you get a great deal on a vending machine and, even with the shipping cost it makes sense to purchase it often sight unseen. You put it out on the street and for a period of time it works great, but then you have it break down on you. You call the person you bought it from who tells you they don’t service the machine or, if they do, it will be a small fortune to send someone onsite to repair the machine. Any cost savings go down the drain.
In some instances, a machine is defective and can’t be repaired. What now? The person you bought it from tells you they are just a reseller and not capable of repairing the machine. To send it back, you need to pay the freight again for it to be repaired. Oh, by the way, they didn’t tell you that parts are currently on back order and that it may be months before your vending unit is functional once again.
