As a shop owner, you can do a quick check before sending customers on their way. If they're buying a device with adjustable airflow, show them where it is and how to change it. Give them the 30-second spiel: "Hot day? Open it up a bit. Cold day? You can close it down for a stronger hit."

Also, keep an eye on your own display units. If you have devices sitting in a sunny window, the heat can affect them too. Rotate stock and keep them out of direct sunlight when possible.

And remember, regulations on CBD products vary by region. What's okay in one state might not be in another. Always check your local laws—this isn't legal advice, but it's common sense for running a shop.

That's the airflow story, plain and simple. Get your customers to adjust, and you'll cut down on complaints and returns. Happy spring selling!
