Discount coupons allow the buyer to get various goods and services for a price that is way lower than the retail price: the discount can reach up to 90%. These deals include clothing, cosmetics, perfume, beauty procedures, photo shoots, theatre and movie tickets, meals, trips and much, much more. In order for the coupon system to work, there needs to be a connector between the seller and the buyer. Those are usually discount websites that offer various deals to customer groups rather than single customers: the discount becomes valid when a certain number of registered users apply for the deal. As soon as the necessary number is reached, all the buyers who applied get a discount code e-mailed to them. The code can later be exchanged for a discount in a shop, restaurant or any other place taking part to the coupon sale. It usually takes the customer a couple of days to get their coupons. Every day new offers appear on the websites; in order to make the search handier, there are always different sorting tools provided for the shoppers to use: you can sort by the kind of products you are interested in, by the amount of the discount, and so on.
