How to compare the total cost of two online offers in Canada
To compare two online offers, match the exact product and seller, convert the charges to Canadian dollars using a dated quote, and add each charge once. Separate confirmed checkout amounts from estimates and unknown costs. If an unresolved charge could change which offer is cheaper, you do not yet have a reliable final comparison.

Make sure the offers cover the same purchase
Check model, variant, quantity, condition, included accessories and seller. A lower amount for an open-box item or a smaller package answers a different question. Record those differences before calculating a total.
Confirm where each order ships from and how it will reach you. Ask the seller if the fulfilment location or import arrangement is unclear. A website ending in .ca does not establish the shipping origin or what charges its checkout includes.
Give every charge a status
Start with the current item amount after any discount you are eligible to use. Add shipping and taxes shown at checkout. Record any prepaid import amount in its own row, then check what the seller says it covers. Do not add an estimated duty amount again if that same charge is already included.
Label each entry confirmed, estimated or unknown, with a URL or quote and date. A line showing zero is different from a blank line. Zero means the applicable terms establish no charge for that line; unknown means you have not established the amount.
For a foreign-currency offer, record the currency and a dated conversion quote relevant to how you will pay. Check the payment provider’s conversion and fee terms. Keep a quoted amount distinct from the amount that will eventually be charged if the rate or settlement timing remains uncertain.
Check imported orders with the right source
For goods arriving by post, use CBSA’s importing-by-mail guidance. It explains the postal import process and directs readers to duties and taxes information. For courier delivery, consult CBSA’s courier guidance and ask the named carrier about clearance charges for that service. Keep mail, courier and traveller rules separate.
CBSA’s duty-and-tax estimator is an estimate for personal-use goods; its page says the final amount can vary and surtaxes are excluded. It is framed around arrival at the border. Do not use its result as a complete quote for a mailed or courier order. These source limits were checked October 28, 2026.
Ask the seller which import charges are collected at checkout and which may be collected later. If there is an estimate, save its scope and exclusions. If a material charge remains unknown, ask before ordering or keep the decision unresolved; do not turn an incomplete subtotal into a delivered-price claim.
Copy this two-offer worksheet
Copy the following rows twice, once for Offer A and once for Offer B. Keep all amounts in CAD for the comparison and preserve the original currency beside the conversion evidence. Complete the sheet privately; it does not require placing an order.
Offer A URL / seller / time checked: ______
Offer B URL / seller / time checked: ______
Identical model, quantity, condition and accessories: ______
For each offer — original currency and dated payment conversion quote: ______
Item amount after eligible discount — amount / status / source: ______
Delivery — amount / status / source: ______
Tax collected at checkout — amount / status / source: ______
Import charges prepaid — amount / coverage / source: ______
Additional uncollected duty, tax or surtax — amount / status / source: ______
Additional carrier clearance or handling — amount / status / source: ______
Confirmed checkout total in CAD: ______
Additional estimates not already counted: ______
Unknown charges and who can clarify them: ______
Comparable delivered total, if established: ______
Compare a return separately
Read the actual seller’s return policy for the item and condition you are buying. Check eligibility, the deadline, how to start a return, who pays return shipping and which original charges are refundable. A marketplace seller may have different terms from the site’s own retail offer; check the applicable policy.
Keep this as a second scenario. Adding return shipping to the normal purchase total assumes a return that may never happen. Instead, record the cost and uncertainty if you keep the item, then separately what you could recover and pay if you return it. Do not assume every delivery, conversion or import charge will be refunded.
Return policy URL and date checked, Offer A / B: ______ / ______
Item eligible and deadline, Offer A / B: ______ / ______
Return shipping payer and known cost, Offer A / B: ______ / ______
Other non-refundable amounts or unknown recovery, Offer A / B: ______ / ______
Choose after checking cost and timing
Compare established totals first. If estimates are involved, state that the conclusion depends on them. If an unknown could reverse the comparison, seek clarification or choose whether the more certain offer is worth its known cost to you. This worksheet does not calculate a customs assessment.
Then check holiday delivery and store pickup against your need-in-hand date. A cheaper offer with an unsuitable arrival estimate may fail your purchase task. Check product price history separately if you want to understand the current item amount.
Use the Black Friday Canada shopping checklist and Cyber Monday Canada shopping checklist for event planning. Recheck both offers before paying, particularly if the seller, promotion, delivery service or basket has changed.
Frequently asked questions
Is a .ca address proof that an order has no import costs?
No. Confirm shipping origin and the seller’s stated import arrangements, then check what the checkout collects and what may be charged later.
Should I add a duty estimate to a prepaid import amount?
Check coverage first. Add only charges not already included; if you cannot establish whether two amounts cover the same charge, ask the seller rather than counting both.
Can I call an offer cheaper if some fees are unknown?
You can compare known subtotals, but state their limits. If a missing fee could reverse the choice, the final delivered-cost comparison remains unresolved.
