Often I see people (who I assume are American) talk about how they used an item for a few days, didn’t like it so returned it.
How does this work exactly? What will the store do with that computer mouse you used for 3 days? Is there a section of the store full of returned items they sell at a discount? I imagine they can’t just put it back on the shelf with brand new stock?
Here in Australia you can only usually return items if there is something wrong with it. Not just because you didn’t like it.
