Oh, interesting topic!
Love strategies!
My H-strategy simply is to plan my purchases in advance and long term to take control of the addiction and avoid to go with a feeling of "oh, I also want..." every time I see something I enjoy
. Like; how many bags do I need/want to own? In what colour/model? I don't want to say yes or get tempted to buy anything else than what I originally decided that I have time to use or get use of.
I also decide what I want for one season in advance, like one bag, one shawl and a pair of boots for example and try to stay with that and don't buy other things. Or I could decided I don't want anything one season, but more another one...
I realize shopping and H is for fun, but addiction needs to be controlled by some discipline ;p
