Shoppers Aid is a productive shopping list app for Windows 8. With this app you can create shopping lists and meal lists. You can push needed items for a meal to your shopping list. Keep track of previous costs so you know if that "sale" is actually a better price. Sort your larger lists by category so you only see those items. You can even print your lists to take with you. Simply enter in the sale and tell Shoppers Aid how many you plan to get and the calculations will be done for you.
