Now, this might seem out of place for a T-shirt, but here's the thing: some apparel brands have age restrictions for certain products, like merchandise with alcohol-related logos. In Florida, selling age-restricted items to minors is a big no-no. So if you're buying a shirt that has a beer brand on it, the seller might require you to confirm you're 21.

That's not something you need to worry about with most graphic tees, but it's worth knowing. If a site asks for your age, it's usually to stay compliant with state laws. Don't skip that step—it's there for a reason.

Also, consider data privacy. When you buy online, your information is shared with the seller. Check their privacy policy to see how they handle your data. It's not directly about returns, but it's part of being a smart shopper.
