Hello,
Three ways are there with which you can set different price for each store view i.e. from admin, by using external extension and coding.
#1 It is possible to set the price for all the store views connected to the same website, especially to set up separate prices for same products for each store view.
You can set the price for your store:
-You can set the price globally
-Also, you get the chance to set price per website (you can have different base currency option and setup a specific price in currency or you may use the currency converter)
The procedure is as follows,
System-> Configuration ->Catalog -> Catalog Price Scope => Website
#2 By using external extension, you can also set different price for your store. Magento default won’t allow you in setting different price for each of the store. So, using an extension like Multiple store view pricing can help you. It will allow you to set and display different price for each of the products in each store view.
#3 With the help of custom coding you can also set the price of the products for your store.
