Any redneck knows much of our deals are done with barter and trade even now.Cash is used if necessary,never check or cards.The ability to provide repairs normally purchased from a dealership shop just on cars alone is an enormous business even now.Most items we use in our everyday lives are currently easily replaced.In the current economy,repairs and time awaiting parts are almost more expensive than purchasing a new item.The material and ability to repair items will be a needed skill and product.
