Starting with a new link
Use First order if the whole process is unfamiliar. Use Link identity if you already have a spreadsheet row but cannot match the source. Category pages identify different physical checks for shoes, clothing, bags and eyewear.
Already comparing an item
Use Measurements for units and endpoints, then Photo evidence for a missing view. Keep visible observations separate from claims that require documentation. Neither guide gives an authenticity rating.
Closer to a payment or shipment
Use Money before checkout to list costs and payment stages. Use Parcel decision for packed dimensions, restrictions and a live quote. If a payment is being returned, Refund evidence helps distinguish wallet balance from original-payment completion.
Questions before you go
Should I read every guide?
No. Start with the question that prevents your next decision and follow the related guide only when you need it.
Do the guides provide live fees?
No. Confirm prices and terms with the current external provider. These pages explain what to check.
