Forms represent one of the cheapest ways you can make the internet work for you. The customer browsing your web site can enter details at anytime of the day or night, and those details can then be processed by you at your leisure, much like you might use an answering machine.
Forms need to be costed individually, but the cheapest are those that generate a formatted e-mail to you each time a customer enters details. If you expect very high volumes, then we would suggest
investing in more sophisticated options that collect the customers' responses into a list.
