How to use this tool
Shipping changes the quality of a deal more than most buyers expect.
Use this tool when
- A store charges a flat delivery fee.
- You are close to the free shipping threshold.
- You want to compare buying one item versus adding another small item.
What to watch
If shipping is a large share of the item price, the deal may stop making sense even if the sticker price looks low.
Fast interpretation
- Low effective shipping rate: usually acceptable.
- High effective shipping rate: compare with a larger basket or a different store.
- Small remaining amount to free shipping: consider whether an extra necessary item improves the basket.
