A seller that follows Ohio's age rules tends to show it in small but obvious ways. You'll notice an age-gate pop-up the moment you land on their site, asking you to confirm you're 21+ before you browse. That's a good start. At checkout, they'll ask for your date of birth or a government ID scan. When the package shows up, the carrier requires an adult signature—no leaving it on the porch.

These steps aren't just bureaucratic. They signal that the retailer takes compliance seriously, which often means they're also careful about product quality and authenticity. If you're a collector, that's worth paying for.

Look for clear labeling on the product page too. A legitimate site will state the age requirement and may link to Ohio's official regulations. They'll also include a physical address and customer service contact—so you know who you're dealing with.
