FAQ
- Can I add multiple items of the same kind without typing them again?
- Yes. Enter the price once and use the + button on that row. Five cans at 78 cents each is one line showing $3.90.
- Can it add tax for a real estimate of what I'm spending?
- Yes. Tap the tax value under the total, enter your sales tax rate, and the total includes tax. Use 0 if prices already include tax.
- Can I enter the amount I have to shop with?
- Yes. Set a budget and a bar shows what is left as you add items. If you go over, the amount over budget is shown.
- How does it calculate buy 1 get 1?
- Choose 1+1 on the item and set the quantity. With 10 cans at 1+1 you pay for 5; with 2+1 and 5 items you pay for 4.
- Can I calculate a discount on top of a discount?
- Yes. The Discount tab takes a discount and an extra discount. 30% then 10% is 37% off in total, not 40%.
