E-commerce templates? Oh, they're just those ready-made website layouts that let your online store look snazzy without you needing a Ph.D. in web design. They make it ridiculously simple to parade your products, keep track of who's buying what (and who owes you!), and effortlessly scoop up all that lovely customer cash. Basically, they let you focus on selling your awesome stuff instead of pulling your hair out over code.
