Reading the fine print or understanding available offers means you could be saving money or taking advantage of refunds or freebies that you might not have otherwise known about, like a brand-new pair of Nike sneakers.

That’s the kind of attention to detail that can lead to some surprising upsides, according to Erika Kullberg, lawyer and founder of Plug and Law, a legal tech start-up for small businesses and entrepreneurs.

Kullberg has found that you could be eligible for compensation for everything from getting bumped from your flight to having a package arrive after its guaranteed delivery date or money off an Apple purchase under its educational pricing.
