Some community groups are printing their own money and buying and selling services and goods from each other tax free. Monopoly money works great. So do IOU's. Barter and trade your skills, services and goods with friends and family. Buy small. Think big.
Instead of shopping at corporate superstores like Walmart, barter and shop at swap meets, yard sales, second hand stores, online stores, family owned businesses and farmers markets. Instead of throwing things out, recycle and repair things.
