What to test in San Marino
Start with a local question. Keep the network, language, and delivery settings separate so the result tells you something useful.
Keep San Marino distinct from Italy in checkout
For San Marino commerce testing, explicitly select the destination country and verify it survives into the order summary. An Italian-language catalogue may share content across the border. That shared interface does not establish San Marino delivery availability or identical checkout conditions.
Compare the requested and observed country
For a San Marino route request, save the geolocation result before evaluating the destination page. If the lookup reports Italy, retain it as a mismatch instead of accepting a familiar Italian interface as confirmation. Product availability and observed exit location need separate checks.
Use a controlled Italian-market comparison
Keep a San Marino delivery address while changing only the proxy origin for the first comparison. Change the delivery country in a second test. Matching product and seller details across both makes it easier to identify whether a difference follows network origin or checkout selection.
