A consumption tax is in Japan.
App "The sharing shopping for lower consumption" was created for those who thought as follows:
"If I distribute it in families and buy it, a consumption tax may lower."
"Even 1 yen wants to lower consumption."
1.It lists the items to buy.
2.If you want to shop at two or more people, you can share consumption tax is lower.
(The more items as large as the number of people shopping, they require time to examine a combination of all, at the time when the combination of low cost and more is found, it will change to the new result.)
3.First, you can and then enter only the number and name of the item, to compensate in the shop (such as discounts) the price of the actual. (That there is no price is not included in your bill)
4.When you have completed shopping, history is recorded. Items you buy often, you can choose from this history.(name and price)
Even when you are shopping alone, Im glad if you can bring them using this app.
