Romell I'm not sure where you work, but this is definitely the exception to the rule. I can assure you that the companies you mentioned uses email. For instance, the advertisements that I receive weekly from each of the stores you mentioned, are sent to me via email. Why is that important? Suppose their advertisement listed a computer for $125, when indeed the computer was $725. A simple typo in the advertisement could cause the company some real dollars if a consumer were to pursue it. They have to honor the advertisement. Of course, as most companies will do, I'm sure they'll pull the merchandise as soon as the error is discovered, but if one consumer happened to push the issue, a loss has occurred. On the other had, all of these stores have multiple locations. They would need a department that's dedicated to making phone calls all day. Have you ever called either of these stores and ask them check if a particular item is available? The wait time is unreal. It would be almost impossible for them to conduct all of their business by phone.
