Best Buy employees don't get commission. When I worked there 5 years ago, management encouraged us to add services to bulk up numbers, but employees never really cared because it never comes back to hurt them if they don't.

For those cables, I doubt you could find an employee that would recommend them to a customer. For accessories, the focus was more on the count attached to an order. Cheap HDMI cables were usually the recommendation because it would add something to the order and customers were more likely to get them over the $100 cables. Those overpriced cables are sold because there is always some customer that only wants to buy the best of the best and Best Buy is glad to help them with that.

So you are likely to get some salesman pressure, but it's not what people think it is. The pushing usually comes when you are checking out and they offer the protection plans. But again, if you tell them no, that's usually the last you will hear of it because it doesn't really mean much to an employee if they don't attach it.

You will find a crazy employee every so often that thinks acting like a car salesman will make them management's favorite person, but I think you could find those people at most jobs.
