Tax disc holders are a perfect medium for advertising a car dealership or brand. This is because advertising literature screen printed onto a tax disc holder can be viewed from both inside and outside the vehicle. However for this advertising to be effective there are a number of basic considerations as to the kind of information that should be displayed. A very simple error is trying to put too much information on the part of the tax disc holder to be seen from outside the vehicle. The secret is to keep it simple. The two major things that should appear on the tax disc holder are the company logo and the telephone number. The main aim is that tax disc holders should be presented in such a manner that the brand or car dealership should be remembered by anyone who views them. It is also a good idea to add a contact e mail address and web address. By doing this there is the opportunity for anyone seeing the tax disc holder to further investigate the products and services provided by the car dealership. Obviously this would also apply to any fleet management companies or insurance companies who also purchase tax disc holders.
