I say it survives by providing the same benefit that Amazon does: a reduction in cognitive overhead.

With Amazon, the reduction comes from the streamlined buying process - you provide your name, address, billing info, shipping info up front, thereby eliminating the overhead of that task from future purchases. It's also a one-stop shop, you don't have to think if they will have an item you want, as 9 times out of 10 they carry a version of what you are looking for.

With Hammacher Schlemmer, the reduction comes from not having to do really any research about products before purchasing. They offer a limited selection of tested products, so you do not have to consider alternative products, sellers, shipping methods, reviews, and are not susceptible to accidentally ordering a counterfeit product. The catalog format is also approachable, you can pick it up and read it and "window shop" without knowing exactly what you want or need.

So I would say not really laziness, just a shift in cognitive overhead from the product purchasing process to the product research process.
