Its limited free trade. Ie you have hard limits on imports per person, ie 1kg of meat, and when crossing you either pay officially hefty import tax on top of 8% swiss vat (which together easily doubles the price) or you are smuggling, and get hefty fine if caught. And they do check frequently on the borders. Inner EU borders see 0 checks (apart from covid era, for covid reasons only) and I am pretty sure you can carry between states much more. That doesn't say anything about warranty, I am 95% sure that it generally works cross borders both ways, ie a lot of Swiss folks order form German amazon and don't worry about return policies. I bought ski touring set from Austrian eshop more than decade ago, found out the boots were slightly too large and exchanged them for smaller, all via post, no imports or other extra fees paid. The shop supported this all explicitly, but its just a bit more paperwork on their side so bigger ones are happy to get your money.
