Compare source photos and observed item prices. Add fit and cost notes when you need them.
Use your selected products?
Your existing notes are still in place. Using selected products replaces them. Export a CSV first if you want to keep a copy.

COST COMPARISON
Add all three cost figures for each option to compare totals. A lower quoted total does not establish better quality.
Make the comparison useful
Compare the same option
Keep the exact size, colour and version with the listing. A headline price may apply to a different option.
Keep unknowns visible
A photo can show a seam or measurement, but cannot establish durability, authenticity or every material claim.
Use complete quotes
Enter shipping and other charges from your actual quotes. This tool does not retrieve agent rates or calculate taxes.
Using source prices and your own evidence
Why is the source price difference separate from quoted totals?
The source difference compares captured USD item prices only. Your selected option, delivery and other charges can change the outcome. Leave your quote fields blank until confirmed; the tool deliberately does not copy a captured price into a purchase quote. The two-order example shows how a cheaper item can have a higher complete cost.
What does a comparison link save, and when should I export CSV?
A selected-product link can identify catalogue candidates; it does not share your private measurements, QC notes or quotes. Those notes stay in this browser. Export a CSV before clearing browser storage, moving devices or replacing notes with a different pair. The visible import choice lets you keep existing notes. See the storage and privacy details.
