Here's a question... To what degree do you think having easy access to an H store or H.com might be fueling frequent buying? And do you think that tweaking shopping habits in small ways, such as taking different routes, might lessen buying?
I live in a small town hundreds of miles from the nearest H store. FedX delivery is problematic in our area for several reasons so I'm reluctant to purchase from Hermes.com. I adore Hermes scarves and would love to buy one but haven't for those reasons. I don't want to buy second-hand and possibly end up with something with snags or spots. So I talk myself out of scarves I love by rationalizing that I don't want the possible hassles that would go along with buying and thus my life is simpler. That doesn't keep me from adoring them from afar and spending too much time window-shopping on the Internet. When a scarf I love sells out on H.com I try to be happy and relieved about it. It is one less thing I want and my bank account is in tact.
Years ago when I gave up smoking I learned that if you make small changes in your daily habits--take different routes, follow a slightly different daily schedule, or simply re-arrange the furniture--you can break yourself of addictive habits. I found that to be the case with shopping. When I got a car it was so much easier to spend lots of money at the mall than it was when I walked there with a backpack.

Nowadays I pretty much stick to shopping by walking to stores with a backpack.
Just some thoughts from someone who is definitely addicted to buying scarves, but hasn't taken the plunge to buy a Hermes one. At least not yet.
