i have heard some say that ' though you see 'sale & discount' tag almost in every shops they get their price' we get nothing as such.
i too think that though you can really think of such shops that gives their customers some relief with brands or labels they purchase , often you find places that charge you more than what the product or the goods, garment, item costs or actual price. but when people step into a shop thinking of buying what ever they like, when they see that banners or labels they obviously feel happy. specially when the customer do not carry much money in her / his pocket he / she may little extra attention to such benefits they can get from their ordinary dealer / shop owner.
some shops display that they give 50% discount , i often wonder how much money they would have paid to purchase the product and why they have charged the product 100%
