Suppliers offer cheap vehicle transfers at irregular intervals.
The reason can be newly built vehicles which need to be transported from their place of manufacture, e.g. In Chicago, to the holiday hotspots. Often the cause can also be the changing demand of certain holiday regions. A supplier then tries to move his fleet into this region and in turn offers one-way rent there cheaply.
Usually, they are referred to as "Relocations" and are offered with a certain mileage and other services - sometimes as low as US$1 per day. Therefore, if you are flexible in terms of your desired time and region, it is worthwhile to visit this site regularly.
Simply select the appropriate rental company.
