I'm not even talking about salespeople upselling you in the store. I am just talking about how their product lines are priced.

For example, a maxed out MBA is just a few hundred short of a MBP. So you say to yourself, well why not just get the pro? That quickly turns into "well I can't get the base model macbook pro" and more. It's all designed so that the consumer instinctively upsells themselves before anyone in the store even tries to do so.
