Introducing a website about counting the cheapest price for product.When shopping for different brands of products, we can use this app for counting the cheapest brand.(Of course, we hope that quality is good,too.) If you went shopping mall like costco, every product is packed of combination. For example,milk cost 10 dollars, and pack of 2 bottle. You can fill cost in the "Cost (dollars)" area, mininum unit(oz,ml) in the "Smallest unit(ml/g/one piece)" area, and 2 in the "Combination of below unit" area. If this product is the combination of 3 pack for sale.(So total 3pack*2bottles) What you have to do is click "plus" button and fill 3 in the "Combination of below unit". When you fill out information of each brand, you press "compare" button and you can get the cheapest one with orange color . "Reset" Button is for cleaning result and then you can start your new comparision.
