SEE THE WHOLE COST
Same product?
Compare the whole offer.
Enter quotes you have checked yourself. Blank shipping or tax stays unknown. Alternatives can be compared, but do not establish the lowest price for an identical item.
Quotes are temporary and remain in this tab. This tool does not check prices, test coupons, store price history or send alerts. Confirm the checkout total and retailer terms before buying.

The lower sticker price can cost more.
Compare the amount due now for the exact same item, then check delivery and returns before choosing. A future reward is a separate benefit, not money removed from today's bill. Leave an unverified charge blank in the calculator above; zero means you have checked that the charge is zero.

Try these fictional quotes
Imagine two sellers offering the same new, single-item model and color. These numbers demonstrate the tool; they are not live prices, retailer offers or evidence of savings.
- Offer A: item $68 + shipping $9 + tax $6 + required extras $0 − usable discount $0 = $83 due now.
- Offer B: item $75 + shipping $0 + tax $6 + required extras $0 − usable discount $0 = $81 due now.
Enter those amounts above and confirm the same-variant checkbox only because the example specifies an identical item and condition. B costs $2 less at checkout despite its $7 higher sticker price. That comparison says nothing yet about which seller is dependable or whether delivery meets your deadline.
Keep three decisions separate
- Money due now: count a coupon only after it actually applies to this basket. Include a necessary accessory or other required charge under extra cost. A free-shipping threshold that needs an unwanted purchase is not automatically a saving.
- Possible future value: if A also promises $10 in store credit for a later order, its current bill is still $83. Record the credit, expiry and restrictions separately. Do not enter it as a $10 usable discount.
- Cost if you return it: record any return-shipping or restocking charge as a conditional cost, not a charge everyone pays today. A cheaper checkout can still be a poor fit when the return window or delivery date does not work for you.

- Seller name, public product URL and date/time checked:
- Due now
- Item + shipping + tax + required extras − applied discount:
- Future benefits

- Need-by date, quoted delivery, return deadline and possible fees:
- Unknowns and decision
- What is still unverified? Buy, wait or skip—and why:
Save only a public product link and your own non-sensitive notes. Keep payment details, addresses and private checkout links out of shared notes. The comparison calculator does not preserve your quotes after this tab closes.
