Tips for a better result
- Name is optionalYou can add an item without a name and it gets a default one. The name only matters when you copy a summary.
- Discount is per itemThe discount applies at the item level. For complex deals like buy 1 get 1, use the discount calculator first and enter the result here.
- Compare price per unitWhen you are torn between pack sizes, check the unit price calculator first, then add the better value to your cart.
How the total is calculated
Each item is price times quantity, minus its discount. The subtotal is the amount before discounts, total discounts is how much came off the full price, and the total to pay is the final amount. Optional shipping is added on top, and the optional 18% tax is applied to goods plus shipping. The average price per item divides the goods total by the number of units in the cart.
Privacy
The calculator runs entirely in your browser. There is no checkout and no payment, no account or signup is needed, and the cart is not stored on our server. When you close the page, the cart simply resets.
