If I understand correctly, once you do the HTO and develop your roadmap, then you're smaller milestones within that path could be potential lower ticket offers that you could then upsell the HTO or other offer... I'd say, that if the upsell focused on a bigger problem within the grand scheme of my initial one and that the messaging was clear that I was still getting what I bought initially, then I'd have no problem at all with the upsell and in fact, if done right, you'll find yourself buying it even though you're expecting it, but it's just so smooth and appropriate that you might not be able to say no :) But yes, if done wrong, it can feel a bit sleazy used car salesmen-like (sorry for those of you selling used cars but some have given a bad rep:) but yea, one of the reasons why I really like the GW formula
