shopping habits

i'm not good at shopping, i think, but i really like shopping, it means i'm not good for electricity.  when i go shopping, i often buy clothes, shoes and so on implusively, finaly there are something to not use, so it is waste of resources. i try to buy products when i go to shopping. Also I buy something that labeled "on SALE" in spite of myself. it causes of buying unnecssary products. In short, I'm bad shopper, so i try to be good shopper. However my family, especialy my mother is great shopper, because she has her shop bag and doesn't buy unnecssary products.
