I used to see a sale and feel like I wasn't doing my part if I wasn't purchasing something. I ended up with the stupidest things, all because they were designer and on sale. Now I really evaluate if I want something, and if I will use it. I've stopped buying designer clothing online completely, since I was buying it, not liking it and not returning it since I didn't want to deal w/ S&H, etc. I don't mind going crazy if it's a good sale and I know I will use the item(s), but I try to really think before I buy now, and that goes for all items, from a gap t-shirt to buying a ton of moisturizer that's deeply discounted but I won't actually use for several months. Sometimes the clutter just ins't worth it!
