Hi,

Our product prices changes each month(January - Product A - 30$,February - Product A - 35$, January - Product A - 25$) and we are left with old stock with old price and new stock with new selling and cost price. As the purchasing cost price changes, we also need to change the sale prices. When new stock arrived, we would be buying & selling in different price than last month. when a customer get a old stock product and if new stocks are available and cashier should have an option to select(Old Stock or New Stock) during checkout. Is it possible to achieve this in Odoo?
