iTaoBuy Spreadsheet
Use this iTaoBuy spreadsheet resource to find category routes and organize product research. Download a blank CSV template, record the original listing and exact option, then check the live details before ordering.
No checkout here. No official brand affiliation.
Where are you getting stuck?
Take the next useful step.
Follow the evidence
Keep the source attached to the decision.
Save the original reference. Match it to the live option. Then decide which question still needs an answer.
Four routes observed on PickFound
Different categories. Different checks.
Flat measurements, cut & option details
Open category guide →Usable space, openings & carrying options
Open category guide →Frame dimensions & limits of lens claims
Open category guide →Start a product research spreadsheet.
Use the blank CSV template to keep a source URL, selected size, QC reference and price date in the same row. It contains column headings only. Add your own references after checking the live listing.
Keep three decisions separate.
Finding a product, reviewing a particular unit, and agreeing to an order are different decisions. A spreadsheet can help you navigate; it cannot settle all three.
PickFound is the external catalog linked from our category guides. We have not established that every PickFound listing can be purchased through iTaoBuy. Confirm the original source link with your chosen platform.
Before any payment, close the gaps.
- Match the source item and selected option to the listing you intended to open.
- Write down the measurement or additional photo you still need.
- Check the current checkout total, return window and available shipping routes.
- Keep a copy of the terms and selected option for your own records. Do not share private order details here.
Questions at this step.
Is this the official iTaoBuy website?
No. This spreadsheet resource is not the official iTaoBuy website and has no official brand affiliation.
Where are the products?
Category guides link to the corresponding PickFound collection. This site does not host a verified product database or sell products.
Does a working link mean an item is reliable?
No. Accessibility only tells you that a page opened. Product identity, seller reputation, stock and quality require separate checks.
Can I download the spreadsheet?
Yes. The free CSV research template opens in spreadsheet software. It is blank: it does not contain verified product records, live prices or inventory.
