To the people in this NYT article who complain that Amazon's customer phone number is hard to find: no sympathy here. Amazon is an efficient marketplace in which, for the most part, consumers sacrifice full service in exchange for lower prices. By withholding its customer service number, Amazon prevents costly hand-holding phone calls and keeps prices low for me.

It's a free market. If people want full service, or are buying something they think may require assistance, they should go elsewhere.
