Actually, if the selection on the website was better, I'd prefer purchasing all my bags online and go to the store for the rest. Unfortunately, this is not the case for the European shop as compared to e.g. the US website.
My SA only works on Tuesdays and Thursdays and due to my work schedule, I usually only make it to the city centre on Saturdays. Hence, going to the boutique during the week requires some planning and shifting of meetings and I've often had to delay my visit to the store as urgent meetings come up on the last minute.
To me, visiting H is stressful, as the commute to the main shopping street is stressful (our office moved basically from being around the corner from H to a couple of kilometers away) and since our city is always extremely crowded with tourists and people from the nearby rural communities. Of course I still prefer touching things and getting inspired, which is why I still try to make it to the store at least once or twice a month, but my office has a post office and I can get everything delivered there.
In addition, since my SA is hardly ever in the store, she either misses out on deliveries or the store only receives negligible stock or stock of products I am not interested in. For that reason, I purchase bags online when I see them popping up, as I know chances are close to zero that I will ever get to touch or see them live at my local H.
For shoes, jewelry, SLGs etc. I am much more patient and the store will transfer products in if needed which is something they won't do for bags (I am not speaking of B/K/C).
