Every ingredient is a pantry staple or impulse buy at any Charlotte grocery chain—mint grows in most gardens or costs $1 at Harris Teeter, limeade concentrate lives in the frozen aisle everywhere, and the rest you've got. The stated five minutes is honest; you're muddling mint and combining four liquids, no hidden prep. At under $1 per drink when made with concentrate, this is genuinely cheap and it reheats nothing because it's meant to be cold and fizzy right now, but that's the whole point. The only slight drag is that fresh mint can be variable in quality and some people find store-bought limeade overly sweet, though both are easy fixes—fresh lime juice costs a few cents more, and homemade syrup takes you past five minutes.
