What to test in Mexico
Start with a local question. Keep the network, language, and delivery settings separate so the result tells you something useful.
Keep Mexican Spanish and market selection explicit
For Mexico localization, retain the original Spanish query and selected storefront country. A Spain or Colombia page may use similar text while serving a different catalogue. Match product identifiers where possible and record the final URL after redirects.
Compare Mexico City and Monterrey delivery inputs
Use supported Mexico addresses with the same basket and retain state, municipality, colonia, and postcode fields as requested. Capture availability and final quote after entry. A Mexico IP cannot set the customer's delivery area or establish city-specific proxy support.
Preserve MXN beside every dollar-like symbol
For Mexico price parsing, store MXN or the explicitly chosen currency with the raw amount, seller, and variant. Keep any installment display separate from the full purchase amount. A US comparison needs matched products and original units before converted prices are useful.
