Well I made a promise to myself that I would try to answer all questions within 24 hours. I have been able to slice that down to about 2-3 hours, which makes my customers and prospective customers very happy. I believe there are many problems or challenges when selling online. There are always a large number of people who are reluctant to give their credit card information out over the Internet. The only way I have been able to handle that is to offer a toll free number prominently on my order page.
People are also wary of the quality of the products and the stability of the merchant.
Without being able to physically touch, feel, smell, etc an item, people generally are cautious. I want people to be happy and I find this usually does help. I started off hosting my site with a company in NY that was taken over by Sage Networks. I was attracted to them due to the low price. That was probably the biggest mistake I ever made.
