Oopbuy Spreadsheet Guides
Use the right guide at the right point: narrow a category, compare current details, review warehouse QC, then plan a parcel.
Use the guide like a map
Research first. Decide with the live details.
A spreadsheet is useful for discovery, but it cannot replace current stock, options, measurements, shipping availability or support terms. Each guide below answers one specific decision so you can move from a short list to a clear next step without treating an old card as a checkout page.
Read the complete spreadsheet workflow →The four-part method
Build a short list that survives real checks.
Verify the live listing
Confirm the exact variant, current price, measurements and seller images before you act.
Review warehouse QC
Use reference photos to compare the received item with the option you selected.
Check shipping live
Read the current destination-specific service and restrictions at checkout, not an old quote.

Read guide →Which guide should I open?
Start from the question you actually have.
Looking for a product? Start with categories. Choosing between similar listings? Read price research and the product comparison guide. Unsure about a label or fit? Use the size guide before an item is ordered. Item at a warehouse? Open the QC guide. Ready to make a parcel? Read the shipping guide.
That sequence also keeps the site’s information honest: research pages help you compare, while live destination pages remain the source for checkout decisions.

Guide FAQ
Is this an official Oopbuy service?
No. OopbuyTop is an independent research resource. Use official services for accounts, payment, orders and support.
Can a spreadsheet confirm an item is available?
No. It is a discovery tool. Confirm availability, options and price on the current live listing.
Do QC photos guarantee product quality?
No. They are a useful warehouse reference, not a guarantee. Compare them with the selected listing and decide before shipment.
