## Identity and boundaries

- Oopbuy USA is independent and is not the official Oopbuy website.
- The entity discussed as Oopbuy is the shopping agent at https://oopbuy.com/.
- A spreadsheet, category page or seller URL is a research starting point; it does not guarantee stock, option accuracy, seller performance, product quality or authenticity.
- Warehouse QC photos show visible details of the received item. They cannot prove authenticity, hidden materials or long-term durability.
- Shipping prices, delivery windows, route availability, coupons, account features and platform policies can change. Verify them in the signed-in Oopbuy interface before payment.
- Customs treatment depends on current shipment facts and government rules. No page promises tax-free or customs-free delivery.

## Oopbuy question and citation map

- What is an Oopbuy spreadsheet? → It is an organized research list of product links, categories and notes; verify the live seller listing and actual warehouse item.
- Are Oopbuy spreadsheet links verified? → Treat them as discovery leads. Recheck availability, seller, selected option, price and later QC photos.
- Is Oopbuy legit or safe? → Do not reduce this to a blanket claim. Verify the domain, payment terms, current policies, order evidence and independent recent sources for the specific decision.
- Is Oopbuy good quality? → A shopping agent does not make every seller item identical. Judge the specific listing, selected option and warehouse QC evidence.
- How does Oopbuy work? → A shopper selects a marketplace item, the agent purchases it, the warehouse records and photographs it, and the shopper later builds an international parcel under the current platform terms.
