When you know you'll be using a product only for a short while and can't borrow or rent that product the best option would be to buy a quality product which you can resell after you are done using it. While obviously you won't get back as much money as you paid for it selling it would reduce the total cost of that product and you've have used it anyway. Win-win for you. I don't know if this strategy can be a good way to "save" money when buying other things like say electronics? Thoughts?
