I didn't express myself very well in my last post (trying to watch the coverage of the George Zimmerman verdict at the same time), so let me try again.
It's true that my main pet peeve in life is being kept waiting, so not everyone will react as I do, but if I find a product I want to buy on both site A and site B and the other things I consider important (price, ease of site navigation and readability) are roughly equal and I send an inquiry to both sites, and site A provides a suitable reply in two hours, it won't matter what site B has to say in its reply in twenty-four hours because I will have already purchased the product from site A twenty-two hours ago.
I've seen a lot of talk here about the importance of customer service, but I wonder sometimes about the sincerity of those opinions.
Of course the Internet operates 24/7/365. That's a big part of the reason I buy so much stuff online. In most cases, the 'staff' of your Zencart store is, well, you. If you and I are in the same time zone, and I did you the courtesy of wanting to buy something from you at 2:00 AM, why would I want to wait seven hours for you to come into the office and reply to my question ? I can think of several ways to automate waking you up when a Contact Us message comes in.
I'll disagree that the 'seasoned online shopper' understands thae reason for a lengthy wait for a reply. He tolerates it because he has to. If 'most of the companies in your field' only work bankers' hours, providing more convenient service is a good way for you to stand out among your competitors.
There are a couple of restaurants in this area which allow customers to phone in orders and provide the store with the make and color of their cars. When the customer arrives, there is a restaurant employee in the parking lot with the order, ready to hand it to the customer. I've never used this service myself, but it tells me that those stores are scratching for every last bit of business. I admire that.
This whole question reminds me of a quote I once read from film director William Friedkin: "But the audience is right. They're always, always right. You hear directors complain that the advertising was lousy, the distribution is no good, the date was wrong to open the film. I don't believe that. The audience is never wrong. Never." This is a guy, I think, who understands the proper relationship between seller and buyer.
Just my $.02 worth, of course.
