I'm not sure I understand the thought behind HH "ruining their name" by having sales. As I see it, they are using a time-tested marketing strategy by selling last season's colors and styles at a discount, to make room for the new fall stuff. From their perspective, it's better to sell them at a discount than have them taking up space in the warehouse, and in the process they can create good, solid brand recognition by putting more HH on the street. I know it's frustrating to buy something and then see it on sale later
, but whether or not they put items on sale periodically does not affect their style or quality, both of which I have found to be very good.
As for whether they are worth full price, it's really subjective. I have gotten some great stuff on sale, and I have paid full price for many name brands, from
Coach and Cole Haan to LV, Balenciaga, Miu Miu, and even (ulp) Hermes. Fundamentally I believe
all of them are way overpriced, but I wanted them enough to do it at the time. Hayden Harnett bags are uncommon and have great style, quality, and details, so it is simply about whether it's worth it to you to pay full price and get what you want, or wait a while and maybe get it on sale -- or possibly have it sell out while you wait, and not get it at all.
