Korea has so many express delivery company aka courier service provider, in which I believe that is the reason why online shopping is popular. It's so convenient, you can delivery almost anything you ordered via Internet, from the regular product of books, cloths, to fresh produce like fruits direct from the farm, meat, seafood, toiletries .... It's really amazing. I have tried ordering pear from the city famous for pear, thus in Korea, you can order special product directly from a particular city, town or village which it is famous for. Also, it is not impossible to get free delivery service for product you wish to buy.
Another thing about delivery company is that, I have noticed a similarity of mascot or character delivery company use to represent their company. Like the example above, they all spotted with a hat or helmet carrying a box and most importantly, the wireless headset. To be honest, I have never seen them wearing any head gear, especially not those cool wireless speaker-phone device. Hmm... marketing branding perhaps? Or the standard stereotype of deliveryman?
