Sorry, don't where you're at. Over here, it's commonly a month return policy of most stores (no law setting this, it's a voluntary thing).
Then there's quite generous warranty for 2 years, up to 3 years, but that's when things break.
In addition, I think this also includes if a sold item is unfit for advertised use, or perhaps even if substantially changed during ownership (eg Samsung mandatorily introducing ads), but I've never had to use that so don't know).
