Thanks you for your help. But I still need something more clear.
Example: I have 10 product to sell and user already bought 2. After that, user swipe data (or buy new device or whatever ..). How do I know 2 id of item which was bought by user. (to prevent from user will select to buy it again, to high light that 2 item when app run in 1st time ... ) Thanks.
